Multiple inlets one outlet how to configure properly?

Post by tjboon »

Hi,

currently getting abit along with CFDof but having trouble with multiple inlets. will show the model for better understanding.

I can either choose to set static pressure to the inlet or outlet, could fil in all velocity values for inlet and outlet.

My question is what is the right way to do this does every inlet needs it own boundery condition or can I put them in as one boundery with 3 faces, if using the latter it seems to creat one long vertical box.

please let me know if you need any other information

also no problem with the meshing part or anything!
