I am attaching the .xml file and the .out file This is the error I am getting and don't know how to solve it: Warning : Level 0 assertion violation # Nonlinear solver not converge in DoImplicitSolve * Newton-Its converged (RES=-nan Res/(DtRHS): -nan with 10 Non-Its) Steps: 672 Time: 6.72000e-01 CPU Time: 10.604s Fatal : Level 0 assertion violation NaN found during time integration. Fatal : Level 0 assertion violation NaN found during time integration. Fatal : Level 0 assertion violation NaN found during time integration. Fatal : Level 0 assertion violation NaN found during time integration. -------------------------------------------------------------------------- Primary job terminated normally, but 1 process returned a non-zero exit code. Per user-direction, the job has been aborted. -------------------------------------------------------------------------- -------------------------------------------------------------------------- mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated. The first process to do so was: Process name: [[52564,1],2] Exit code: 1 -------------------------------------------------------------------------- Any Help or comment will be extremely appreciated.
