Hi everyone!

My supervisor is very cryptic...a solution of one of my models is not reaching convergence after more than 10k iterations. After telling me to keep on with patience for many days, today he told me to "play with computational parameters" such as type and number of numerical scheme and multigrid cycles. Where should I look? How should I change these parameters?
Thanks in advance
