Either you do the post-processing inside Fluent and there you need to start with at least -gu .driver null or to post-processing separately on the cluster using CFD-Post or EnSight. I am not sure if your cluster management allows you to do interactive things. For that reason you always can use batch post-processing with CFD-Post.https://forum.ansys.com/discussion/comment/97447#Comment_97447

My cluster does allow me to connect with an interactive GUI. But, I am most interested in batch post-processing via CFD-post. My aim is to produce a .wmv file from the velocity contours of my solve at each time step, with the time value labelled.nIs there any documentation or tutorials you'd recommend to read up on this?nThanks so much for your help @DrAmine, !n
