[Getfem-users] Question about non-linear terms

[Konstantinos Poulios]

Hi,

I have noticed that for nonlinear terms in an assembly procedure there
are two places for them to refer to mesh_fem objects. The first one is
the constructor function of the nonlinear term, where references to
mesh_fems can be stored inside the object of the nonlinear term. The
second one is the assembly command where definitions like
NonLin(#1,#2) let the nonlinear term refer to the first and second
mesh_fem which are contained in the assembly procedure. I cannot
understand this mechanism very well. What are the mesh_fem numbers
inside NonLin() used for? Is there any documentation of the NonLin
mechanism?
