Hello all,
I am attempting to write a program to solve parabolic PDEs via implicit finite differencing in VBA. I am currently solving the systems with Gauss-Seidel. It is my understanding that using successive over-relaxation can significantly speed convergence of the solution assuming that the coefficient matrix is diagonally dominant.
I am curious if people have opinions on the effectiveness of this strategy, and if it is a good one, if anyone has VBA source code to calculate the over-relaxation parameter and implement in the solution.
Thanks and best rgds.
