Hi,there!
If you have exprerince in using pressureboundarycondition3D,I need your help.
When I set const pressure value to one side of a box,and other side were set to freeslip .there will be velocity in the box.But the four edges of inlet( the pressureboundary ) have velocity=0,which will make the model error after several steps.
If you meet the samilar problem,we can have a communication.
