The solid is currently assumed incompressible (the solid pressure is not
updated) and in general would be near incompressible so internal energy is a
more appropriate energy choice than enthalpy which would require a pressure work
term currently not implemented. Additionally due to the way in which the
conduction is handled in terms of the gradient of energy the accuracy of the
current enthalpy implementation is sensitive to the pressure distribution as
this introduces an enthalpy gradient from the p/rho term which would need to be
corrected; this issue is avoided by solving for internal energy instead.
This improvement requires the scheme and solver settings for the solids in
chtMultiRegionFoam cases to be changed from "h" to "e" and the thermo-physical
properties in <solid>/thermophysicalProperties to be set to the corresponding
internal energy forms, e.g.:
thermo eConst;

energy sensibleInternalEnergy;
All tutorials have be updated to reflect this and provide guidance when updating
cases.
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:
settings: core settingsaliases: aliases for interactive shellsunset: sourced to clear as many OpenFOAM environment settings as possiblempi: MPI communications library settingsensight: application settings for EnSightparaview: application settings for ParaViewscotch: application settings for compiling against scotchmetis: application settings for compiling against metis 5
The config.*/example directories contains various example configuration files for the corresponding shell:
compiler: an example of fine tuning ThirdParty compiler settingsopenmpi: an example of fine tuning openmpi settings for OpenFOAMparaview: an example of chaining to the standard config/paraview with a different ParaView_VERSIONprefs: an example of supplying alternative site-defined settings
