[petsc-users] how to translate a FEM problem to PETSc

[Ted Sariyski]

Hi,

I wrote an unstructured vector finite element electromagnetic solver, 
which among other modules, includes domain decomposition and (complex) 
GMRES solver. Now I am working on improvements and I would like to 
migrate the code to PETSc. I am new with PETSc. I am still working 
through the examples, trying to figure out a 'proper' entry point for 
integration. My current understanding is that domain decomposition and 
the assembly will remain outside PETSs. I already have the 
global-to-local/local-to-global data structures built. My difficulty is 
to figure out how to translate them to PETSc compliant format. I'll 
highly appreciate if somebody points me to examples illustrating how to 
translate a FEM problem to PETSc.

Thanks in advance,
