I really appreciate the help, unfortunately I am completely lost on what you are describing and in trying to find this hidden feature. I understand the concept somewhat but I can’t find any documentation on the process in SimScale. I’ve have searched the forums to see how to change the scheme to localEuler. I can only assume that it is already doing it for me since I have LTS selected. I’m still really new to CFD (Only maybe 20 hours on ANSYS before using SimScale?) and have never used OpenFoam. I still thank you for the time you have given, I just hope my hours don’t run out during this last sim.
