Hi, I am solving Poisson's equation Div. Grad(Phi)=rho in the (R,Theta) plane with KSP, and it is working well if I avoid the axis. But I would like to put a point at R=0. Is there a recommended way to do that? Thanks, Sean

By the way I forgot to mention I am using finite differencing, not finite elements. Thanks, Sean
