I am currently running a steady 3D K-Epsilon Realizable Simulation, I run the simulation for around 20,000 explicit iterations and then switch to implicit for another 10,000.
The simulation runs fine in explicit as expected but when I switch to implicit the simulation crashes, I have tried reducing the CFL number to 1 from 5 but it still crashes. The simulation orginally runs in 2nd order schemes but I am now swicthing that to 1st order to see if that helps. I was just wondering if anyone has any ideas that could possibly help it run in implicit? Possibly incease explicit iterations to around 25,000 or 30,000 to increase convergence? |
