Hi @ggiraldo, I just saw your reply and it helped me a lot. I do have a follow up question though:
I’m running a numerical wind tunnel test of a thin membrane structure. The membrane doesn’t have a thickness (in real life it is 1-3 mm thick) so when I extract the result as you are suggesting in what direction is the pressure then acting? When the wind is hitting the surface it will be pressure on one side and suction on the other side and since I only get one pressure value for each point I assume that is the difference of pressure and suction. That is all good but I need to know in what direction it acts.
Thankful for help here.
