gf_model

model variables store the variables and the state data and the description of a model. This includes the global tangent matrix, the right hand side and the constraints. There are two kinds of models, the `real` and the `complex` models. model object is the evolution for getfem++ 4.0 of the mdstate object.

# Calling Sequence
