[deal.II] Trilinos::Amesos_Superludist not scaling across multiple nodes

2022-07-14 Thread Paras Kumar
Dear dealii Community, I am working on solving the a nonlinear coupled problem involving a vector displacement field and a scalar phase-field variable. The code is MPI parallelized using p:d:t and TrilinosWrappers for linear algebra. Usually I use CG+AMG for solving the SLEs when solving for e
