Hello, I have created my own block sparsity pattern by adding non-zero entries manually, and then compressed it. Upon some testings on this sparsity pattern, I have realized that it is indeed created correctly, in terms of dimension and number of elements it has. However, the system matrix that I initialized with this sparsity pattern looks empty (system_matrix.m() = 0). What would be the possible reason for this? Thanks for any response in advance,
sparsity_pattern.reinit(4,4); if(something happens) sparsity_pattern.block(0,0).add(local_dof_indices1[i],local_dof_indices2[j]); //these kind of operations sparsity_pattern.compress(); system_matrix.reinit(sparsity_pattern); -- *Mustafa Ağgül* *Department of Mathematics* *Michigan Technological University* *1400 Townsend Drive* *Houghton, Michigan 49931-1295* *Tel: 906-487-3135* -- 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.
