I have looked into that a bit more today and it seems there is everything we need available (finally). Then i'd have another question regarding the use of FEMSystem. What would be the actual use case of choosing FEMSystem vs. the approach in most examples? I have used the normal example approach be

[Libmesh-users] Just assembling matrices and residual vectors with libmesh

2016-08-31 Thread Julian Andrej
Hi, so we are elaborating FEM libraries for a project we are attempting. One requirement is, that we want to assemble FEM matrices/vector into PETSc objects, which libMesh obviously provides. Is there a way, to just assemble the matrices by providing element based loops, so that we can work with t
