Hi
Could any body tell what happens if we simulate transient phenomenon using steady state simulation method in fluent. For eg. if we simulate vortex shedding using steady state conditions what will happen after N iterations and what will happen after N+x iterations. Will the results be different (I mean different positions or number of vortices)? How does fluent treat it internally? Do N iterations mean the flow output will give us phenomenon happening after time=N*time step size? |

steady state solver doesn't involve time variable.

At least you will not make residuals go down. And -mAx- is right.... if the flow is unsteady - you can not solve it like steady-state problem.
I personally tried (just to see results) to solve flow with vortexes as steady one - It is not possible! |
