Hello,  
I represent the CFD team of LiU Formula student where we use ParaView for postprocessing. The python script runs with no errors capturing all the images on interactive mode. However, the following error seen in the image is encountered when run on batch mode. The equation used was for Cp\_tot, which is not a complex equation. The aim is to reduce the minimize the computational resource usage.  
Looking for some reasonable suggestions…
