Dear All, The following system of equations: KQ=R where, [image: Screenshot from 2022-08-22 13-45-45.png] were solved using BlockSparseMatrix to form tangent matrix K. It was solved by:
SparseDirectUMFPACK A_direct; A_direct.initialize(K); A_direct.vmult(Q_stp, R); Now, I'm trying to run my code with MPI using PETSc/Trilinos, but the solver does not except PETSc/Trilinos BlockSparseMatrix. How do we solve such a general system of equations? -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
