Extend the OGS-MFront interface

Overview

• Introduced a new class MaterialLib::Solids::MFront::MFrontGeneric, which supports a variable number of input and output data of the material model.

  • MaterialLib/SolidModels/MFront/MFrontGeneric.cpp
  • MaterialLib/SolidModels/MFront/MFrontGeneric.h

• class MaterialLib::Solids::MFront::MFront is now based on MFrontGeneric. Therefore, much code has been moved away from the files

  • MaterialLib/SolidModels/MFront/MFront.cpp
  • MaterialLib/SolidModels/MFront/MFront.h
  • Note: The interfaces of MFront and MFrontGeneric differ very slightly. In particular, the generic interface cannot implement MechanicsBase<DisplacementDim>, because it's more generic. Therefore, there is still a bit of code in the MFront class.

• Both classes basically have the same configuration. Therefore, lots of code have been moved:

  • MaterialLib/SolidModels/MFront/CreateMFrontGeneric.cpp
  • MaterialLib/SolidModels/MFront/CreateMFrontGeneric.h
  • MaterialLib/SolidModels/MFront/CreateMFront.cpp

• Added an example MFront behaviour (by @nagelt, cf. OGS CM talk), currently used in unit tests

  • MaterialLib/SolidModels/MFront/ThermoPoroElasticity.mfront

• On the OGS side, input data is passed via MaterialPropertyLib::VariableArray. The necessary settings are specified in

  • MaterialLib/SolidModels/MFront/Variable.h

• Added several unit tests that check the data passing between OGS and MFront. They require additional MFront behaviours that are only used for unit testing.
