[petsc-users] Doubt about TSMonitorSolutionVTK

[MIGUEL MOLINOS PEREZ]

By the way, the hdf5 format works and I have the vtk library installed in PETSc.

Dear all,

I want to monitor the results at each iteration of TS using vtk format. To do so, I add the following lines to my Monitor function:

char vts_File_Name[MAXC];
PetscCall(PetscSNPrintf(vts_File_Name, sizeof(vts_File_Name),
"./xi-MgHx-hcp-cube-x5-x5-x5-TS-BE-%i.vtu", step));
PetscCall(TSMonitorSolutionVTK(ts, step, time, X, (void*)vts_File_Name));

My script compiles and executes without any sort of warning/error messages. However, no output files are produced at the end of the simulation. I’ve also tried the option “-ts_monitor_solution_vtk <filename-%03D.vts>”, but I got no results as well.

I can’t find any similar example on the petsc website and I don’t see what I am doing wrong. Could somebody point me to the right direction?

Thanks,
Miguel
