Thanks! This is very useful to us to study the secular evolution of galactic discs should you care to know :-)

comment Numerically solving Helmholtz equation in 3D for arbitrary shapes
Sorry to bother you again: I am confused why is the PDE not involving D[u[t, x, y], t] == Laplacian[u[t, x, y], {x, y}]-u[t,x,y] i.e. why does it not have u[t,x,y] on the r.h.s. ?
