Thanks, it helped me. Very small mesh elements are still disordered but oweral solution looks better. Regards, Oleg Kmechak On Tuesday, 30 April 2019 17:38:49 UTC+2, Wolfgang Bangerth wrote: > > On 4/30/19 7:29 AM, Oleg Kmechak wrote: > > PS: In a moment I checked documentation for write_vtk.

Hey everyone, I got a problem regarding TrilnosWrappers::BlockSparseMatrix. In my program I have a TrilnosWrappers::BlockSparseMatrix system_matrix which consists of two parts, one permanent part, which is computed at the beginning at the programm, not every iteration, to save time (called
