Dear Matthew, thank you. That makes much more sense. Is the script you mention available for download? Thanks, Miguel On Jul 1, 2024, at 5: 09 AM, Matthew Knepley <knepley@ gmail. com> wrote: On Mon, Jul 1, 2024 at 1: 43 AM MIGUEL MOLINOS

<div>Yes, I get output when I run the example mentioned by Barry. </div>

<div>The output directory should not be an issue since with the exact same configuration works for hdf5 but not for vtk/vts/vtu. </div>

<div>I’ve been doing some tests and now I think this issue might be related to the fact that the output vector was generated using a SWARM discretization. Is this possible? </div>

<div><br>
</div>
<div>Yes, there is no VTK viewer for Swarm. We have been moving away from VTK format, which is bulky and not very expressive, into our own HDF5 and CGNS. When we use HDF5, we have a script to generate an XDMF file, telling Paraview how to view it. I agree that
this is annoying. Currently, we are moving toward PyVista, which can read our HDF5 files directly (and also work directly with running PETSc), although this is not done yet.</div>

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 “<span style="white-space: nowrap; box-sizing: border-box; color: rgb(123, 45, 90); font-family: SFMono-Regular, Menlo, Consolas, Monaco, "Liberation Mono", "Lucida Console", monospace; font-size: 13.125px;">-ts_monitor_solution_vtk</span><span style="color: rgb(123, 45, 90); font-family: SFMono-Regular, Menlo, Consolas, Monaco, "Liberation Mono", "Lucida Console", monospace; font-size: 13.125px; background-color: rgb(255, 255, 255);"> </span><span style="white-space: nowrap; box-sizing: border-box; color: rgb(123, 45, 90); font-family: SFMono-Regular, Menlo, Consolas, Monaco, "Liberation Mono", "Lucida Console", monospace; font-size: 13.125px;"><filename-%03D.vts></span>”,
but I got no results as well. </div>

<span>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?</span></div>
