===============================
User changes
------------
- Many minor changes (see detailed ChangeLog).
- Allow user definitions of head losses by zones (see cs_user_head_losses.c).
- Do not relax k and epsilon by default when using Bl v2 k turbulence model.
- When inserting boundaries (shuch as thin walls), vertices are now separated
on each side of those boundaries, for a true topological mesh modification.
cs_user_mesh_thinwall is also renamed to cs_user_mesh_boundary.
Numerics
--------
- Improve time stepping of the coupled solver for the components of Reynolds
stress tensor (irijco = 1).
* No clipping on Rij should appear when no flux rectonstruction is needed and
an upwind scheme is used (except those due to boundary conditions on R12).
* Add eigen_max function to cs_math.c
* EBRSM and SSG models are treated.
* Add a clipping indicator which can be activated to check where clipping
occurs in the output files
- Add and reorganize convection schemes (especially for VOF method)
* reorganize Roe-Sweby limiters.
* add Compressive convection schemes for accurate modeling of free surface
with VOF method.
- Add a conservative gradient reconstructed with least squares gradient for
vectors and scalars, in place of iterative gradient initialized by least
squares gradient (imrgra=4,5,6).
- Add a cooling towers module to simulate exchange zones.
- Add a convection-diffusion equation solver for additional vector variables.
Physical modelling
------------------
- Add a Volume Of Fluid algorithm:
* partly merge cavitation algorithm with VOF algorithm.
- Add data assimilation feature to atmospheric module
(optimal interpolation and nudging):
* copy LU utilities to cs_math and keep static inline version of them
in cs_sles_it
* an optimal interpolation structure is created
* interpol grid and measures set structures are used as well
* multidimensional analysis are computed for multidimensional variables.
- Modification of the LES dynamic Smagorinsky clippings.
- Add internal coupling for scalars of two domains (for instance temperature
between solid and liquid, or enthalpy for electric arcs between plasma and
weldpool).
- Add sorption model treating non-equilibrium between solid and liquid phases
to the ground water flow module.
- Lagrangian module:
* add deposition and resuspension models on internal faces.
The user can the impose the motion of deposited particles. If integral
approach for porous modelling is set up (iporos=3), then the internal fluid
section is reduced by particle deposition.
* injection is now pseudo-continuous when injecting at every time step.
To revert to the previous behavior, the CS_LAGR_RESIDENCE_TIME value
must be set to 0 for newly injected particles.
* 2 new attributes, CS_LAGR_TR_TRUNCATE and CS_LAGR_TR_REPOSITION, may
be used to visualize particles with trajectory errors, rather than
remove them. Particles are now only removed when "completely lost",
which should never happen.
GUI changes
-----------
- Add handling of multiple compute builds through the GUI.
- Add mesh extrusion capability to the GUI.
- Add a notebook to add global variables to be used in the GUI (such as variables
in the physical laws).

Architectural changes
---------------------
- Renamed Autovnv to studymanager.
- Remove dependency to Qt of GUI XMLengine.Case class, used by studymanager.
This dependency was introduced in version 3.0.

for movable builds, a CATALYST_ROOT_DIR environment variable may be used.
- Added general structures to handle boundary and volume zones.
- Extended run staging and submission to coupled cases. Temporary status file
is now in execution ad not scripts directory.
- Add handling of lmod-based environment modules.

as libhdf5 (when built with CMake)
- Add functions for definition of mesh groups during mesh preprocessing.

- Replaced icond keyword by icondb, icondv to allow to enable wall condensation
and condensation on internals at the same time.
- Probes output activation is now based on field "post_vis" keyword, and does
not allow fine-grained per-variable probes selection anymore (this being little-used,
and feasible through use of additional probe sets).
- Prepared for cs_user_extra_op and cs_user_parameters translation to C in VnV base:
* removed Fortran arrays corresponding to members of cs_var_cal_opt_t C structure
* deployed use of get/set var_cal_opt everywhere

* removed iprpfl indirection array between field indices and properties
numbers; iprpfl is kept for compatibility but is just an identity
function (hence still known in user subroutines);
* irom, iviscl, etc.. are now directly field indices (hence starting from 0)
* test on variability of specific heat (icp), isochoric specific heat (icv)
and volumetric viscosity (iviscv) are consequently shifted of 1
(-1 : uniform field, >=0: non uniform)
* renamed _owner utility subroutines
* renamed most used add_property_field into add_property_field_1d
* mesh viscosity now a 3-dimensional field when strictly orthotropic
* removed iroma, ivisla, ivista, icpa variables; previous values of these
fields now accessed by field_get_val_prev subroutine.
- Removed global_row number from matrix structures, as it was never used,
and could cause confusion with global ids such as those used with
range sets (which are realy used in some cases).
- Added range set structure, to ease operations related to handling of an
owning rank for distributed entities.
- Added matrix assembler structure, to allow more general assembly of
matrices, especially in parallel cases with rows matching elements
shared on ranks (needed for parallelization of CDO operators).
- Refactored parallel numbering for space-filling curves and added
a numbering generation based on a 1D series of real values.

A priori, could be used only if the thermal turbulent flux was solved.
- Fix initialisation of flux and divergence boundary coefficients for coupled
vector variables (field with dim=3).
- Many more bug changes (see ChangeLog for details)
Release 4.3.0 (July 29 2016)
============================
User changes

visualization output (cs_post_mesh_set_post_domain function).
- Automatic computation of head loss for a given volumic zone.
- When using boundary condition zones defined by the GUI, error reporting
for overlapping zones is improved, with associated visualization.
- When extruding boundary faces, the group class id of interior faces
previously on the boundary may by kept as an option.
This is the default using the GUI.
Changes
-------
- Turbomachinery module: for better restart behavior, the joined mesh
is now also handled using checkpoint/restart.
- GUI: remove titles from profile definitions, as these were only handled
by the obsolete Salome VISU module.
- Added some turbomachinery post-processing utility functions.
- Allow coupling of radiative transfer with 1d wall thermal module.
- Extend automatic postprocessing output to fields defined at vertices.
- Add boundary mesh extrusion function callable from user subroutines.
(in case of periodicity, rebuilding the periodicity in a later
preprocessing stage may be necessary).

cs_selector_get_i_face_num_list, it is no longer necessary to build
selection mechanisms during the optional mesh modification step.
Numerics
--------
- Add optional multigrid solver for scalars with convection and diffusion,
based on the PhD work of Sana Khelifi.
- Lagragian module: new trajectory algorithm which does not loose particles even
for warped faces (cs_lagr_tracking).
- Improve robustness of Boundary conditions for wall functions of scalars.
Mainly impact Atmospheric flows.
- Add many convective flux limiters for convective schemes:
* Fix in Convection scheme when the density is variable and the theta
scheme is 1/2 so that the scheme is now conservative over time.
* add inline functions for vectors
* simplify non-relaxed inline functions
* use inline functions for temperature explicit balance (bilsct)
* Add an add hoc limiter, called Beta, which ensures that, for any
convective scheme and any time stepping, that the variable remains
between "min_scalar" and "max_scalar", to be given by the user.
* Implementation of the Roe-Sweby Limiters for all the convective
schemes (Original SOLU, CENTER, Standard SOLU)
* Creation of a new keyword: kst, for key source term;
we use it to add source terms in the Beta limiter
- Handling of linear solver errors is improved to allow re-try with
different solvers or parameters.
- Default to multigrid-preconditionned conjugate gradient for
most symetric linear systems.
- Improve performance and possible precision of reduction operations.
* improve OpenMP load balancing of SuperBlock reductions

Architectural changes
---------------------
- Added parallel IO for MED output when underlying MED library is built
with parallel (HDF5) IO support.
- Extend control file mechanism with Python module communicating through
sockets (which may in turn be extended by an RPC mechanism); the
commands are currently limited to connecting, advancing a time step,
and disconnecting (in addition to control_file commands), but may
be extended.
- Simplify MEDCoupling output writer so as to generate MEDCoupling meshes
on the current partition rather than aggregating them to the root rank,
as this should soon be directly usable by a VTK adaptor.
- Convert Lagrangian and radiative module implementations to C.
This affects the associated user subroutines.
- Add basic (non-GUI) support for OAR resource manager.
- Add mesh adjacencies structure to allow direct access to a cell's
neighbor cells and boundary faces. This allows looping on
cells, as when computing a SpMV product using a CSR matrix,
rather than looping successively on faces.
- Improvements to postprocessing writer handling.
* add 'plot' and 'time_plot' writer types;
* time plot flushing behavior is now determined by the
cs_time_plot_set_flush_default() function, replacing the
Fortran 'nthsav' and 'tplflw' values;
* writers can now use the 'separate_meshes' option to create a
separate format-specific writer per mesh.
- SALOME version required for MEDCoupling is now version 8.0
in this version, MEDCoupling is a full standalone library and may
be used separately from the MED module.
Release 4.2.0 (December 23 2015)
================================
User changes
------------
- Automatic initialization of the Turbulence for EBRSM and k-omega models.
From a reference velocity (uref), the turbulence profiles are reset
after the first iteration. The velocity magnitude is also changed
so that the Reichard profile is imposed next to walls.
Activate it with reinit_turb=1 (in usipsu).
- Merge the bad cell and the mesh quality criterion for offsetting.
- Merge general boundary temperature handling with the radiative
"wall temperature", for unified logging and post-processing.
- Added optional saving of scalar variable boundary values as fields
(also done for temperature when a property).
- GUI: "check mesh" option is replaced by a new "preprocessor view": when
building a new case, the GUI only shows sections relative to mesh
selection and preprocessing, showing only the steps necessary up to
preprocessing. "Tools" menu entries and toolbar icons allow switching
from the preprocessing mode to the computation mode.
This new view encourages users to use the "preprocessing" run type,
which was previously available at the end of the GUI options,
instead of the "check mesh" option, which did not handle batch runs
or user subroutines.
- Add boundary cell thickness computation to mesh quality criteria.
Physical modelling
------------------
- Add gas mix thermo. and fix mass source term with the compressible module
(internship of A. Menasria):
* allow to select both gas mix (igmix) specific physics with compressible
(icompf) spec. physics
* add property field for deduced mass fraction (iddgas) and mixture molar
mass (igmxml)
* add a field pointer mapping for gas mix (mapping mix molar mass field)

deduced species
* add Sutherland behavior law for viscosity and thermal conductivity of
gas mix (ivsuth option)
* move setting of ieos from uscfx1 to usppmo
* add thermo. relations for perfect gas mix in compressible thermo.
(also for BCs),
* igmix specific physics triggers switch of ieos to 3
* treat conduction term in total energy equation correctly in gas mix
(Cv depends on species)
* fix mass source term in compressible (momentum source term coming from
added mass has to be accounted for in simplified momentum equation during
mass balance step).
- Add precipitation/dissolution modeling for particle tracking.
- Add the added-mass term in Lagrangian particle tracking (activate it
with iadded_mass=1).
- Add FSCK radiative model for coal combustion.
Activate it in cs_user_parameters.f90 with imfsck=1.
- Add a wall function for the velocity based on scalable wall function
which is valid for both rough and smooth walls (activate it with
iwallf = 6 in cs_user_parameters.f90).
Moreover, the continuous wall function based on Van Driest (iwallf=5)
is extended to Eddy Viscosity Models, and the use of roughness is allowed.
For both wall functions, roughness must be specified in the field nammed
"boundary_roughness" in cs_user_boundary_conditions.f90 for instance.
Numerics
--------
- Add new preconditioning management layer to allow for use of multigrid
as a preconditioner.
- Extend weighted coefficients for lsq gradient calculation in case of
anisotropic diffusion (this option can be enabled with the option
iwgrec(ivar) = 1).

stress model (irijco=1).
* convection diffusion brick for tensors
* add a gradient of a tensor field
* only iterative methode up to now, least square gradients not yet
available

Improve the computation of discrete Hodge op. when using
conforming reconstruction function.
Adapt the computation of the source term when using this kind of discrete
Hodge operator.
* Add time scheme and make some factorizations in vertex-based schemes.
Add functionalities to cs_locmat_t structure.
* Add convection for CDO vertex-based schemes.
Add advection field along with its post-processing.
Two advection operators are available related to the conservative or
non-conservative form of the advection operator.
Add post-processing of an equation (i.e. that of the related field).
* Add different ways to enforce boundary conditions for CDO vertex-based
schemes. Weak (Nitsche) enforcement, penalization and strong enforcement.
* Add a domain and an equation structures
Move cs_param_eq_t structure as a member of the cs_equation_t structure
* Add the computation of the wall distance for CDO vertex-based schemes
* Add the computation of the wall distance for face-based CDO schemes
* Change the way user sets the paramters of a computation
* Integrate PETSc solver calls
* Add face-based CDO schemes for pure diffusion problem.
Architectural changes
---------------------
- Add --compute-build option to "code_saturne run" command to allow choosing
one of several compute builds at runtime.
- Add "code_saturne submit" command to submit a batch job.
The GUI now uses this to prepare data upon submission.
- Some renames and simplifications in matrix fill types:
* to make things more generic, CS_MATRIX_33_BLOCK* is replaced by
CS_MATRIX_BLOCK*
* tuning for blocks assumes 3x3 blocks, but a specific CS_MATRIX_BLOCK_D_66
type is added (as a subcase of CS_MATRIX_BLOCK_D) to allow for specific
tuning for RSM coupled component matrixes.
- When using old (non-parallel) algorithm to compute wall distance, save
distance in same array as for main algorithm.
- Implement handling of point and element tags so as to ignore location
on elements sharing tag.
- Simplify Lagrangian particle tracking, removing a linked list.
This is transparent for the user, except for a possible differences
in particle numbering.
- Major changes to all_to_all API, so as to make its usage easier.
* new API is similar to cs_part_to_block / cs_block_to_part, so
as to be aligned more with sparse or neighborhod collectives
then Crystal Router in the future.
* place Crystal Router code in separate files from cs_all_to_all,
to allow lower-level use. Also simplify its usage, and make its
data access logic higher level.
- Added cs_debug_wrapper.py debugger wrapper, to assist in running the code
under a gdb-based debugger, under Valgrind, or a combination of the two.
* replaces the "valgrind" only debug in the GUI advanced options for execution.
* may also be used in standalone mode.
- Do not build with BLAS by default, as only MKL is used outside of unit tests, and
using it requires providing its path to "--with-blas" anyways.
Release 4.1.0 (July 31 2015)
============================
User changes
------------
- Renamed 'efforts' to 'stress', which should be less confusing.
- Add simple fan effects modeling as explicit momentum source term in
regions defined by fan characteristics.
- Add a code icodcl=11, allowing to easily impose a boundary value
consisting in an affine function of the next cell value
(used at wall faces in the compressible module).
- Add timer statistics and plots for different stages and operators.
* Base timers for each time step (with initialization as time step 0)
are now available in the timer_stats.csv file (or timer_stats.dat
if the default format is changed).
* Final performance data is also moved from listing to performance.log.
- Allow condensation model to use zone-based definitions. The examples
are updated so as to recommend the zone-based setup, though previous
single-zone setups definitions remain compatible.
- Add "--import-only" option to "code_saturne create" command so as to
rebuild SaturneGUI and runcase scripts for a case which was copied
from a different system.
- Add higher level functions for turbulent boundary condition settings.
This allows moving tests on the current turbulence model inside
the user-callable functions, for more concise and safer programming.
Physical modelling
------------------
- Add 2-scales wall function (with V. Driest mixing length) and its consistant
wall function on scalars (keyword iwallf in the doc.).
- Changes in Lagrangian Particle tracking.
* modification of multi-layer model (iclogst = 1)
* compute porosity in each cell based on mean deposition height only
at boundary faces (porcel.f90)
* influence of deposited layers on the flow (iflow = 1 option); addition of
laghlo.f90 to compute the head loss due to deposition based on porosity)
* remove lagbar.f90 (energy barrier now computed by cs_lagr_barrier for
smooth wall/irough = 0, and cs_lagr_roughness_barrier for rough wall/
irough = 1).
- Add stiffened gas thermodynamic law for the compressible module (ieos=2).
Two new parameters are accessible in the user subroutine uscfx2:
gammasg ("pseudo" specific heat ratio) and psginf (infinite pressure).
- Add ADF models for radiative transfers.
Numerics and linear solvers
---------------------------
- Add vertex-based CDO (Compatible Discrete Operator) numerical scheme
for diffusion problems. This is a first step, and does not handle
parallelism yet. Integration with the rest of the code will be improved
progressively.
