Does anyone know of a place where I can find a simple 1D axisymmetric code like:

1/r*d/dr(1/r*dU/dr)+S=0

with Neumann BC on one side and Dirichlet on another side.

I appreciate ur help.

Hi, john 1. Sorry I can't tell you the code location but your problem is rather simple you just need to integrate twice. 2. Check the equation, if there was Laplace operator in cylindrical case it comes to 1/r*d(r du/r)/dr. Best wishes
