V13.3.15 of 14 October 2022

1. User interface:
   - Reorganisation of model configuration file to support direct user browsing.
   Backward compatability maintained.
   - The full use of the graphical display area in Prj is enabled by moving clipping
   from 'eye space' to 'screen space'. This fixes problems relating to drawing
   outside the display area.
   - Added ability in prj to copy obstructions between zones.
   - Revised descriptors for flow component types as used in flow network reporting.
   - Refinement of markdown reporting of model contents and Res-generated tables.
   - New materials and constructions added to respective databases.
   - Added user option to set the assignment of inside and outside surface heat
   transfer coefficients (also available as a simulation options in bps).
2. 3D model manipulation:
   - Extended E2r to work with ESP-r generated Wavefront object files.
   - Added option during export to Wavefront object files to specify if a polygon
   represents the inside, centre or outside face when considering the overall
   thickness of a construction.
3. Miscellaneous:
   - Fixed bug in the topology checker that corrupted surface boundary information.
   - qrun facility removed because it duplicated facilities found elsewhere.
   - Added new topics to the model contents report.
   - Refined Res monthly reports.
   - Updated data structure and interface to thermal bridge facility.
   - Continuing refinement of exemplar models and addition of thermal bridges to
   some models.
   - Various trivial bug fixes.

V13.3.14 of 21 February 2022

1. Revised file formats and databases:
   - System control files, with upgrade to optical control to replace the
   control embedded in zone tmc files, extend sensor types and also allow
   multiple day types.
   - Zone construction files to merge zone tmc files.
   - IPV directives now located in a separate file in the msc folder.
   - Model upgrade facility updates old formats (although these can stil be read).
   - Special materials results, as stored in the results database, is now the sum of all
   such materials present in the zone.
   - Added new PV module to components database.
   - Added new blinds to optics database.
2. Exemplar models:
   - Training, validation and tester models updated.
   - New weather files added and some existing files updated to include atmospheric pressure.
   - Model variant facility updated to accommodate recent changes to monthly vs embedded shading.
3. External reflections (via modish):
   - Fix to bug preventing modish running in monthly mode.
   - Mod to allow the monthly mode to be called once only for many zones.
   - All modish modes can now be activated for specified zones and surfaces.
   - Two exemplar models added to the 'model' folder, one for embedded (time stepping)
   operation, the other for monthly operation.
4. Model export:
   - Extended export of wavefront files to allow individual placement of bodies to the
   centre line, inside face or outside face of the zone polygon.
5. Occupant modelling:
   - Refinement of 'dynamic people' type casual gains in zone operations.
6. Integrated CFD:
   - Introduced new CFD blockage boundary condition type, 'casual gain'. This allows
   representation of a solid heat source (or sink) in the domain, e.g. a computer, and
   dynamic conflation with a casual gain type in zone operations.
   - Introduced new CFD blockage boundary condition type, 'occupant'. This
   allows representation of an occupant in a CFD domain and the dynamic conflation
   with occupant heat gains. The feature requires dynamic people in zone operations.
   - Multiple CFD source BCs can now be linked to a single contaminant network source,
   distributed by prescribed fractions (a common use case is CO2 release can now be
   distributed among multiple occupants in the domain).
   - Streamlined CFD-to-contaminant network coupling.
   - New CFD domain file (.dfd) format V2.3 introduced to accommodate above changes.
   - Disabled CFD opening zero gradient boundary conditions until a fix in its aberrant
   operaion can be developed.
   - Tightened CFD flatlined residual detection criteria to try to prevent the premature
   halting of simulations. The CFD flatlined residual detection criteria is now
   proportional to the convergence criterion, rather than a percentage change.
   - Changed default CFD solution setup to a more widely applicable configuration.
