Author	SHA1	Message	Date
Mark Olesen	622f476b32	ENH: additional SHA1Digest constructors and methods - data_bytes(), size_bytes() methods to support broadcasting or gather/scatter content. Additional construct from raw bytes to support transmitted content.	2023-03-20 11:36:50 +01:00
Mark Olesen	7389ce15ce	STYLE: readOnProc/writeOnProc instead of 'valid' for IO	2023-03-16 11:20:09 +01:00
Mark Olesen	f801e99f9e	STYLE: use readValueEntry in BCs. Assign Zero for refValue/refGrad	2023-03-16 11:20:08 +01:00
mattijs	34e36b83ab	ENH: initEvaluate()/evaluate() for faePatchField, fvsPatchField - no-op implementations, but makes the call to GeometricBoundaryField::evaluate() less dependent on PatchField type - add updated()/manipulatedMatrix() methods to faePatchField, fvsPatchField etc. These are mostly no-ops, but provide name compatible with fvPatchField etc.	2023-03-16 11:15:35 +01:00
