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?
