[Trilinos-Users] Example of FE assembly - Epetra_FECrsMatrix

[Robert Simpson]

Hi all,

I’ve been trying to find an example of how to assemble local (FE) sub matrices into an Epetra_FECrsMatrix but I’m struggling to find anything other than the simple example in didasko/examples/epetra/ex23.cpp which creates a diagonal matrix using one process.

Is there any code which demonstrates how to do this? Something which demonstrates looping over elements using multiple processes and how to map these to the relevant entries in the Epetra_FECrsMatrix?

Apologies if this an obvious question.
