Hi
I am trying to aplly a pulsating load of about 300psi in the back side of a diaphragm which is used to pump fluid. i am struggling in defining the boundry conditions such as stroke length, and no. of strokes per minute of the piston. How and where can i find the correct reference for this?
Thanks
anthony.
Are you trying to set up a static study or non-linear? The static study will not give you the results you are looking for and I don't think non-linear handles time-step. What are you simulating (stress? displacement? fatigue? volume change? fluid?) and we will be better suited to help.
