Does Simulation offer a non-uniform pressure distribution with polar coordinates instead of a quadratic based? I have two flat discs sealing in compression which fluid pressure breaks down from the OD to the ID. The pressure drop can be determined most easily by assigning a radial relationship... hence the polar coordinate system would the easiest answer. If not then how can I use the cartesian coordinate system for a circle with the constants only being assigned to either a liner or a parabolic relationship (only goes to x^2 or y^2).

Also, I noticed that the axisymmetric 2D simplified simulation does not offer non-uniform distribution. This would be so nice to have in my circumstance where the pressure is normal to a disc surface and changes via a radial distance relationship.

Is there another "place" where I can enter my own equation from scratch?

Thanks!!

hi wayne, unfortunately none available currently, please submit an enhancement request through the customerportal. you'll also find the answers to your questions there in the kb.

the only workaround is to break your surface up and apply equations or pressures as close as you can. ie, break it into a bunch of rings and then apply discrete pressures.
