Pressure Time derivative

jiggypepper · December 22, 2015, 10:59

I have a transient model of a damper with a moving piston. I would like to no where the highest rate of change of pressure is throughout the model. How do I plot this graph or get this information. I have tried the monitors and derivatives, but I can only find dp-dx and dp-dy. What I need is dp/dt, and to find the maximum value of dp/dt (and which area this value occurs at) through the model as the simulation occurs.

Thank you so much for your time.

Hello Ahmed, did you find a solution for this problem?
