Solving 3D heat equation with an off-center boundary condition
So i have this code (albeit a simplified version but it'll do for this question)which solves a time dependant 3D heat equation on a cylinder.
r1 = 0.001;
r2 = 1;
h = 1;
m = 1.5; (*some parameter*)

Problem computing a cylindrical Heat equation with a parameter alpha
i have been struggling to compute a particular instance of cylindrical 3D heat equation.
Here is my code :
(*parameter*)
\[Alpha] = 0.1;
h = 1;
eq = D[u[t, r, \[Theta], z], t] -
D[u[t, r, \[ …
