Hi all, I have four differential equations to be solved with a linear sparse matrix system that has the form of "(mat)A dot (vec)X = (vec)B". For each node, I have dof=4. I found few tutorials or examples on the KSPSolve with dof>1, and I do know it's possible to solve this problem with Petsc. Are there any sources illustrating ksp solver with dof>1? Many thanks!
Sorry for the stupid questions. -- Best regards,
