Basically I need to evaluate the rotational velocity and pressure of water rotating in an axilsymetric pipe while being time dependant. I've thrown together some code that I thought would work, but I keep getting a memory protection fault error (yes I have the new version) and I'm just not sure what I'm doing wrong. Thanks Rotating Pipe pipe2.pde (2.1 k)   Robert G.

FlexPDE is supposed to tell you this. I will have to dig into the code to see why it crashed instead... If you provide a Vr equation, the crash will go away.
