Optional fixes for the OpenFOAM installation

As described below, there are different optional fixes depending on whether you are using OpenFOAM.org, OpenFOAM.com, or foam-extend. The replacement files are in the OpenFOAM-9, OpenFOAM.com and foam-extend-4.1 directories. Run ./Allcheck (with export S4F_NO_FILE_FIXES=0) to list the files that differ from your installation, or ./Allreplace to copy them into $FOAM_SRC, then rebuild the affected libraries.

OpenFOAM.org

  • FixedList.C: This fix is required for newer compilers.

  • GeometricField.C: this fix is required for consistent time discretisation. Some FSI cases may crash without this fix.

  • backwardDdtScheme.C: this corrects the scheme for a moving mesh, for example, for the fluid domain in a fluid-solid interaction simulation.

OpenFOAM.com

One copy of each file in OpenFOAM.com is used for all supported OpenFOAM.com versions (v2312 to v2606).

  • backwardDdtScheme.C: this corrects the scheme for a moving mesh, for example, for the fluid domain in a fluid-solid interaction simulation. The scheme falls back to Euler while a field has no old-old time level, instead of only on the first time step of the run. Apart from this change, the file is the same as the upstream file, which is identical in v2312 to v2606.

foam-extend

  • FixedList.C: This fix is required for newer compilers.

  • meshObjectBase.H: without this fix, all runs will end in a segmentation. The solids4foam solver will work correctly; however, you may like to fix this if you plan to catch the return valve from the solver.

  • pointBoundaryMesh.C: without this fix, cases involving topological mesh changes will have a segmentation fault. For example, when using crackerFvMesh.

  • EulerDdtScheme.C: This corrects the scheme for a moving mesh, for example, for the fluid domain in a fluid-solid interaction simulation.

  • backwardDdtScheme.C: this corrects the scheme for a moving mesh, for example, for the fluid domain in a fluid-solid interaction simulation.

  • GeometricField.C: this fix is required for consistent time discretisation. Some FSI cases may crash without this fix.
