This new constraint type is preferable to the 'empty' type used previously as it support patch field values for post-processing and other purposes. The internalFvPatchField operates as a 'zeroGradient' type so that the adjacent cell values are displayed on the faces exposed by the sub-setting. The internalFvsPatchField operates as a 'calculated' type so that the internal face values are displayed on the faces exposed by the sub-setting. The immediate benefit of this change can be seen when using 'subsetMesh' without the '-noFields' option to create and write a sub-set of an 'fvMesh' with field values, now the face values of the 'exposed' internal faces can be visualised.
OpenFOAM Configuration
The main OpenFOAM settings are located in the parent etc/ directory. The bash and csh shells are supported and to configure OpenFOAM source etc/bashrc or etc/cshrc respectively which source the following files in the config.sh or config.csh respectively:
