Attached are two files: one with a slip solution and the other with a no-slip solution, both on the same mesh. I want to compute the difference between these two solutions using the append attribute (if there is another way to compute the difference, please let me know). Please help me in this regard. I have tried to use the methods available on the discourse, but they didn’t work. I am a beginner in ParaView. Hope to hear from you soon.
