25.2.3 Bug Fixeds/Improvements

Fixed a bug where the Time Stepping Method was set to Adaptive but behaved as Fixed when calculating transient simulation. (This bug occurred during the program update process.)
Changed the Age calculation method : There were some cases where solution doesn’t converge because the relaxation factor was not applied. We changed it to use the relaxation factor of momentum. We also changed the tolerance from always applying 1e-4 to applying the convergence criteria of momentum.
User-defined scalar calculation method change : The bounded was applied to the discretization scheme to improve stability.

Return code error when exiting Solver and Utility in Windows version: When calculating collateral fields such as y+, Q, Age and so on, the fields are created normally but do not function properly. In batch run mode, calculations for each condition are completed normally, but errors are displayed. This is a problem that occurred during the process of building the OpenFOAM code for Windows, and we will resolve it as soon as possible.

BaramFlow

Built-in Post-processor : Graphical post-processing functions that used Paraview are now supported.
Transient density-based compressible solver: The density-based compressible solver, which was only available for steady-state, is now available for transient analysis using the dual time step method.
Additional Boundary Conditions: It is now possible to input wall roughness and use radiative heat transfer conditions using wall external emissivity as well as convection from the wall to the outside.
Added non-orthogonal corrector: You can now set a number of non-orthogonal correctors for numerical methods.

BaramMesh

Directional level Increment: Added the ability to increase the size level only in a specific direction of the coordinate axis by castellating the mesh.
Castellated buffer layer: Added the ability to create a buffer layer similar to a boundary layer on certain boundaries.
Export to 2-dimensional/axisymmetric mesh now supports multi-region mesh.

Initialization speedup: Improved the speed of initialize before starting a calculation.
Improved the area of the cell zone condition page and the way cell zones are displayed to improve user-friendliness.
The default value for the number of processors now uses the last value set.
Improved the order in which boundaries are displayed by sorting them by name to improve user-friendliness.
Added a feature to check if MPI is properly installed on the system during installation. If there are any problems at startup after installation, a popup will notify you.
BaramMesh can now import geometry files with names that are all numeric or contain non-ASCII characters.
Upgraded the version of the VTK library to 9.4.

Fixed Mass weighted average bug: Fixed a bug that prevented mass weighting from being applied in monitoring.
Fixed a bug where it was not possible to set a user variable for the Scale of Velocity on initialization.
Fixed a bug that prevented the ability to limit the phase of a user-defined scalar from working.
Fixed unnecessary flow variable values appearing in the solid region when initializing a conjugate heat transfer problem.
