Hey guys I am new to comsol and I am trying to plot either in a table or a graph where the max erosion occurs (angle) in a 90 degree elbow in a pipe. The variable I am trying to plot is fpt.phii and I know exactly where the point is on the geometry, I try to put a cut point 3-D at that point but it always gives me an error reading: comp1.fpt.phii undefined variable. Is there any way where I can have Comsol give me the value of that angle at that point? Thanks.
