Hi all

Did any one try using Lower Upper approximate factorization in Finite volume method for Diffusion equation. I am facing some trouble with this . I actually tried in Finite Difference method in 1D,2D as well as 3D it worked fine but using FVM its creating trouble.

I would like to know how the boundary conditions for the gradients of del_Phi are approximated in FVM using this implicit LUAF.
