kamaljannati New Member kamal jannati Join Date: May 2019 Posts: 1 Rep Power: 0	hi everyone i tried to write a code in fortran for solving the usual Cavity problem with finite volume method, approximate factorization ADI technique. But i have a Problem in running the code. my code works look well with mesh 2020 or 2222 or 24*24. But for any other meshes my code diverges immediately. The Flux Integral is correct because it work well in runge kutta 4th order Explicit method. Can anyone help me with this problem?
