Dear All
I have implemented a local time stepping method that allows different time steps on different cells. In this method the unsteady results are valid. But still the CPU time is the same as explicit time integration. (The total number of loop needed is the same as explicit method with a adjustable time step ). I want to eliminate the calculation of div and grad and the same member of fvc to decrease the CPU time. In fact when the grid is becoming so large this technique will show great efficiency. I appreciate any guide and help. Best Mahdi |
