...since my last message saying I was running the simulation again and saw a 2nd peak I changed max number of iterations per times step from 20 to 5 and reran it... not sure why but that second larger peak did not show... however, there are a few subtle rises and lowerings.. but definitely nothing clearly cyclical is present... see pic below. Also the velocity and pressure contours seems much better, right?...
Any thoughts?
