Hey Jean-Paul Thanks a lot, Now it works finely. Best regards Gabriel Gabriel Peters Endenicher Str. 310 53121 Bonn 00491525/5478185 gabriel.pet...@koeln.de Am 20.05.19 um 15:01 schrieb Jean-Paul Pelteret > Dear Gabriel, > > It looks to me like you forgot to dereference the shared pointer

Re: [deal.II] Problem Solving BlockSparsematrix system blockwise

Dear Gabriel, It looks to me like you forgot to dereference the shared pointer for the preconditioner. So, solver_gmres.solve( system_matrix.block(0,0), distributed_solution.block(0), rhs.block(0), *Mp_preconditioner); // <— here You probably have the same problem for the other call.

Re: [deal.II] Interpolate correct solution onto mesh using interpolate() with FE_Bernstein elements

I wrote a drop-in function which can replace VectorTools::interpolate, but works for both FE_Q and FE_Bernstein (not tested yet for other elements). Is it useful to have something like that in the library, and if yes, what is the best way for proof-checking and integrating? Thanks! Am

[deal.II] Problem Solving BlockSparsematrix system blockwise

Hey everyone, I have a problem at solving a blocksystem. I have a matrix called "system_matrix" in Blockform M = [[A,0],[B,C]] and I want to solve classical Mx = F. (F = [f,0], x = [x1,x2]) I proceed according to the LinearSolvers class in the step-32 tutorial. so by blockwise solving the
