Dear all, I am trying to solve a similar problem as step-29 but including the massive parallel solution as presented in step-40. I would like to ask how the solve() function would be in this case.
In step-29: //LU decomposition and inverse matrix SparseDirectUMFPACK A_direct; A_direct.initialize(system_matrix); //Solve with inverse matrix A_direct.vmult(solution, system_rhs); When applying massive parallel computations, my initial guess was: LA::MPI::Vector completely_distributed_solution(locally_owned_dofs,mpi_communicator); //LU decomposition and inverse matrix SparseDirectUMFPACK A_direct; A_direct.initialize(system_matrix); //Solve with inverse matrix A_direct.vmult(completely_distributed_solution, system_rhs); locally_relevant_solution = completely_distributed_solution; However, I get a *no matching member function for call to 'vmult'* error. How can I use this LU decomposition and inverse matrix solver using MPI?
