Dear all,
My unsteady flow simulation taking around 2 months to converged the solution. How can I reduced CPU time for unsteady problem?  Thanks. |

how big is the grid?
just my two cents, try * use smaller grid solution to initialize the big grid. (search "interpolation file" in manual) * use biger time steps to develop the flow for a while, then switch to smaller time step. * use parallel computation. * use implicit solver |
