R2020A

This version is the same as beta2020.09.0. For a detailed list of differences compared to R2019.1.0 (same as beta19.10.1), see Beta.

New:

• RepresentativeMassAlgorithm and VOLUME_correction_local: Improvements and bugfixes.
• EULERIMPL: Improvements and bugfixes.
• New Encryption functionality.
• ERFHDF: Improvements and bugfixes.
• Ucv_DEFAULT.dat as a general chance to define general simulation defaults. See __DEFAULT_configuration_file__ .
• Default definitions for alias names, such as "in*_DEFAULT". It is a generalization of the deprecated "default"-alias definition. See AliasForGeometryItems .
• New INTEGRATION statements %SUMMATION_INT% and %SUMMATION_BND%.
• Completed begin_save{} environment.
• New parameters restart_path and restart_file, see RestartPath.
• New CommandLine option -lcs, --check-license.
• exportGeometry{: Writing of OBJ files by groups.
• New functions eigen() and nbsum() in Equations.
• MEMORIZE functionality works now with restart

Bugfixes:

• Multiple bugfixes and improvements for stability and performance.

R2019.1.0

This version is the same as beta19.10.1. For a detailed list of differences compared to R2018.1 (based on beta18.05.0), see Beta.

New:

• improvements to GASDYN solver.
• Improvements to DROPLETPHASE solver.
• Redlich-Kwong Gas Law for modeling real gas behavior (in LIQUID solver, see PhysicalProperties).
• New feature %HEAT_EQ_1D_BC% for using 1D heat equation as temperature boundary condition (see HeatEquation1D).
• New feature RepresentativeMassAlgorithm.
• Improved MPI Shared Memory support, e.g. for GEOTREE2 and MONITORPOINTS (see COMP_SharedMemoryForBE, COMP_SharedMemoryForGT2).
• Improved support for ERFHDF5.
• Support for version 4.1 .msh files for triangular 2D meshes from Gmsh.
• Performance improvements for geometry operations, see GeometryOperations.
• new manipulate{ - feature: extrude{
• TWOSIDED is now deprecated, use duplicate{ and thickenabs{ instead
• New option for ReadInPointCloud: writeOut, see WriteOutManipulations
• New INTEGRATION feature Skip.
• New EVENT handles %EVENT_WriteResume% and %EVENT_SaveResults%
• New CommandLine option --exec-dir, -e.
• New CommandLine option --clparam, -clp to be used as system variable @CLPARAM@.

Bugfixes:

• Multiple bugfixes and improvements for stability and performance.

R2018.1.1

Bugfixes:

• Fix bug where INTEGRATION values were all zero when organization steps were skipped.
