Hi Jennifer, I fixed a different bug in step-32 related to n_dofs() a few minutes ago and now step-32 runs correctly for me.

We are using a custom MPI_Op in the code and that is triggering an error for you. Can you update deal.II and run step-32 in debug mode and see if the error is still there? If yes, can you tell me what MPI library and what version you are using (or try a different recent one)? -- Timo Heister http://num.math.uni-goettingen.de/~heister _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
