calculate the hysteresis of pressure vs time in diadem

[chandler]

I have a signal file of pressure vs time and need to calculate the hysteresis. What would be the best way in diadem to do this?

Hi Chandler,

Am I correct in assuming that the first part of the signal is the rising pressure and the second part is the falling pressure, and that your ultimate goal here is to find the difference in area between these two curves?  If so, the following forum post which involves force/displacement hysteresis contains an example which can probably be modified to fit your needs:

I hope this helps, and let me know if you have any other questions!
