Hi all,
I've written a program that solves the Poisson equation in
an irregular mesh, using a finite volume discretization.
the method works well, and the solution is very good at a
distance of 2-3 mesh sizes off of the source.
The problem is that I need to know what is the contribution
of the nodes to their neighbors- a place too close to have an
accurate solution (i.e. m/r)-
my question is, how could this be calculated? or- is there
a method to impose the influence to be m/r?
Thanks in advance,
Ariel.
