I want to program a finite difference algorithm in Matlab to solve the time dependent reynolds equation. I'm not really experienced in numerical simulations and want to know which algorithm, the SOR or ADI, is the best (calculation time, stability etc.) for solving this problem. So my question is, which scheme, SOR or ADI is the best for solving an elliptic problem?

Can anyone give an answer on this question?

ADI Is an implicit method but SOR is an explicit method. SOR is easier. But the speed of convergency for this scheme is low. I prefer ADI, which is more robust.
I hope this would be useful.
