I have not run an example for an unstructured grid. It should work similarly though. I recently wrote a Catalyst adapter for an unstructured grid. I will run Catalyst Live with that to see how that works. You could try however to save images or entire data from the pipeline script as it is done in the Catalyst examples. > A few more questions come in my mind now: > - If I understand correctly and if the user wants to pause the simulation, > for example when he has only 1 timestep, he would have to do the following > steps: > * Connect with catalyst in Paraview > * Set a breakpoint for time step 0 > * launch the simulation > Is that alright ? > Would it be possible to do this with the play/next frame paraview buttons ? > The communication between catalyst and the simulation happens only at time steps. Because of that, Catalyst could only stop the simulation at time step 2. - Looking at the last lines of the blog post concerning pvserver.
