Hello Rui, hello Mathieu,
thank you for sharing the answers to the question. I am currently with the same issue.
I tried using the Python Calculator to solve this problem.
One dataset is a time averaged LES simulation and one is an RNG simulation. The geometry of both simulations is the same. From both simulations I extracted the necessary time step and then applied the Python Calculator. Unfortunately I don’t get a result. This might be due to incorrect input data?
Can you help me with that?
