unv2oofem: Added PlaneStress2DXFEM in unv2x.py
Added initial implementation of ScalarFunction, added corresponding parsing support in input records. Variable cross section migrated to ScalarFunction implementation, tested on tests/sm/truss2d_01.in
Merge branch 'master' of www.oofem.org:/data/git/oofem
Added __pycache__ to gitignore.
Changed to direct calls to LoadTimeFunction::__at(..) in a few places (in preperation to conversion to generalized Function classes).
Simplified tokenizer. Split up if-clause in readToken function into 2 separate functions.
Added function wrappers for time functions and added function for evaluating general functions.
Changed many C-style casts to C++ style casts which offer better warnings if things go wrong.
Fixed warning in enrichmentitem.
Added scalarfunction.C and moved implementations over there. Added missing << operator and missing entries from DynamicInputRecord. Removed unnecessary union (?) to enable std::string which simplifies the code.
Renamed LoadTimeFunction to TimeFunction. Added default implementations for functions of more than just in time.
Renamed some derived Functions to more accurately describe what they are.
Added missing file "scalarfunction.C" from 3 commits back.
Fixed roporting IP values to Gauss points in each iteration. Added missing values to giveIPvalue().
Reverting previous changes in vtkexportmodule.C
Added generalized evaluate() method to CalculatorFunction.
Renamed some leftover "ltf" to "tf".
Changed FloatArray return value to parameter in Function::evaluate.
Added convenience function to ScalarFunction for use when just time or coordinates are sent as parameters.
