Excuse me, I solved the two-dimensional hydrostatic pressure field solid.p. The hydrostatic pressure solid.p distribution is not uniform. Use d(solid.p, x) to solve the partial derivative of solid.p along the x direction. Why is the calculation result 0?

I think I have found the problem, when I use X instead of x in d(solid.p,x), I solved it. The X and x are different in comsol.
