[Getfem-users] Add integration method

[Torquil Macdonald Sørensen]

Hi!

I have created a custom mesh_fem, and I made it available in my program using 
the code

getfem::add_fem_name("CUSTOM", custom_fem);

where custom_fem is a function that returns a getfem::pfem, similarly to how it 
is done for the built-in mesh_fems in the Getfem source code.

I select this mesh_fem using the syntax

mf.set_finite_element(getfem::fem_descriptor("FEM_CUSTOM"));

However, now I would like to create my own integration method IM_CUSTOM to go 
with FEM_CUSTOM. My goal is to define an integration method that is exact on 
FEM_CUSTOM.

Is there a nice way to do this without recompiling the Getfem source code? I 
didn't find any functions analogous to "add_fem_name", but for integration 
methods rather than mesh_fems.

Best regards
