Solve failure with no information #16615
-
My solve fails after multiple time steps without producing any error messages. The solution fails on the second nonlinear iteration. Here is the output using '-snes_converged_reason -ksp_converged_reason -ksp_monitor_true_residual -ksp_view': Performing automatic scaling calculation 0 Nonlinear |R| = [32m6.158493e+01[39m After this line the program exits with the following response on the command line: application called MPI_Abort(MPI_COMM_WORLD, 1) - process 0 I'm not sure how to go about debugging this issue, so any help would be greatly appreciated. Thanks! |

My guess here is is that you have crossed up your MPI installations somehow (i.e. you are compiling/linking against one MPI and running with a different one). Can you describe what your installation process was like? |
