This release contains a lot of improvements in all processes and also new material properties. Mostly bug fixes and documentation and procedures improvements. Stay tuned for the next major release 6.4.0 featuring new processes implementations.


  • You can <include file="../path/to/file.xml"> other XML files into a .prj-file. !3081

Process' changes

  • Reactive transport process:
    • allow to assign chemical formula alternative to a component when defining water composition. !3122
    • output equilibrium and kinetic reactants (immobile phase) in amount. !3138, !3141
  • Heat Transport BHE process: allow to specify a flow and temperature control condition with the BHE inflow rate and temperature values both following the corresponding curves. !3125
  • ThermoHydroMechanics:
    • The storage is now derived from the fluid density and the solid bulk modulus. !3159
    • Fix bug in temperature equation for non-zero velocity. !3193
  • HydroMechanics: Allow linear shape functions for displacement. !3334
  • Use MPL properties in HeatConduction process. !3062
  • Fix bug in deactivation of subdomains !3065
  • Exterior forces output in LiquidFlow and HeatConduction. !3068
  • Allow thermal expansion to be anisotropic in ThermoHydroMechanics process. !3107
  • Improve generic interface for updating medium property variables. !3262
  • Improve generic interface for computing secondary variables. !3227
  • Component transport process: output flow velocity averaged over integration points. !3254

Boundary condition and source terms

  • Added a special Dirichlet boundary condition called "SolutionDependentDirichlet". The value assigned for the boundary condition is dependent on the process solution of last time step. !3085, !3123
  • Cleanup of source term implementations (use volumetric source terms for line source terms). !3233


  • Changed the way to pass dot x for staggered scheme. !3082
  • Add dotx to postNonLinearSolver. !3164
  • The extrapolators now accept an empty integration point values vector, in which case these are ignored. For now relevant only for LIE/SD process. !3117
  • LIE; Update Heaviside function to [-1/2,1/2] range. !3140


  • The "Function" type parameter becomes independent from a domain specification, i.e. it is not any longer possible and necessary to specify a domain via a mesh tag !3054
  • Extend the "Function" type parameter to handle time in the expressions introducing the t variable, additionally to the currently available x, y, z. !3054
  • Pass curves to the "Function" parameter, such that they can be used in expressions like curveA(sin(t)). !3058
  • Increased the tolerance for |A|=1 test in coordinate system. !3203

Time stepping

  • Fixed bugs in the fixed time output. !3026
  • Removed the fixed output time data from time stepper classes. !3080
  • Allow time stepping continue after nonlinear fails in the staggered coupling loop. !3106

Material models

  • New material models:
    • strain dependent permeability !3236
    • relative permeability model 'RelativePermeabilityUdell'. !3290
    • saturation dependent thermal conductivity. !3298
    • permeability model 'Kozeny-Carman Model'. !3264
  • Linear, saturation dependent swelling stress model. !3096
  • Pass variables from previous time step to MPL Property::value() calls where increments are required. All *rate variables were removed in
    favor of the increments. !3102
  • Use 2D coordinate system for LinearElasticOrthotropic solid material. A bugfix, now allowing 2D anisotropy and solid material orthotropy to be used simultaneously. !3165
  • Unused MPL properties are shown as warnings after successful run in debug mode. !3197
  • Error message now informs user of missing properties on the medium scale. !3337
  • Bugfix of a 2D case in MFront's implementation of Mohr-Coulomb-Abbo-Sloan anisotropic model. !3260
  • Update interface of the solid material models now accepting MPL Variables. !3261

File I/O

  • New optional output format XDMF:
    • light data is written into .xdmf file and heavy data into .h5 file. !3184
    • reduced number of iNodes for HPC applications and removed redundancies in file output. !3246


  • Refactored insitu-functionality for VTK 9 / ParaView 5.8. The mpi container generated by the CI job now contains this functionality. !3092
  • partmesh tool now exports "vtkGhostType" array indicating duplicate cells. !3111
  • Fixed ghost element bug #3035. !3299
