[Libmesh-users] Creating a Petsc matrix and vector

[Prashant K. J. <pjh...@gm...>]

Hi All,

I was wondering if there is a way in LibMesh to create a petsc vector and
matrix given the number of DoFs and sparsity? I have a 1D-3D coupled
problem and to create a resulting block matrix, I am relying on GMM
library. It would be nice if I can create a block matrix (one block for 3D
field in LibMesh and another for 1D field on 1D network) in Petsc and use
its parallel computation feature. Any suggestions are welcome.

Thank you.

Regards,
Prashant
