Hello everyone, I got an issue when I want to run IncNavierStokesSolver while I am giving the initial conditions from a filed data file as: <FUNCTION NAME="InitialConditions"> <F VAR="u,v,w,p" FILE="IC.fld"/> </FUNCTION> The "IC.fld" was generated from the following interpolation using parallel FieldConvert: mpirun -np 256 FieldConvert -m interppointdatatofld Grid.xml IC.pts IC.fld where "IC.pts" comes from u,v,w,p from a fully turbulent 3D data. When I'm running the IncNavierStokesSolver with the following command: mpirun -np 256 IncNavierStokesSolver Grid.xml Conds.xml I'm getting the following error: Fatal : Level 0 assertion violation A parallel solver must be used when run in parallel. ------------------------------------------------------- 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: Exit code: 1 -------------------------------------------------------------------------- Everything works correctly if I don't run in parallel. Has anybody seen such issue? I would extremely appreciate it if you can help me with that.
