I have a water storage tank that I am trying to simulate a pressure pulse though. The tank should be a closed control volume in actually, but SolidWorks requires input/output boundary conditions consisting of an inlet flow of some sort and a pressure boundary of some sort. So, basically I have a pipe instead of a closed volume. I set up my problem as a transient internal flow calculation and am getting results, but the method is flawed. Has anybody attempted anything like this?
