Can you explain more about your case? It would be easy to point out a solve that might suit your case.

@paritosh
the flow is through a model of turbine stator cooling network . like the one in the link below. http://3.bp.blogspot.com/-KYC-Nn3g5B...Q/s1600/29.JPG It is a single inlet ,multiple outlet flow. It is steady state incompressible turbulent flow using K-epsilon. In my simulation Pressure is not converging. I am presently reading about AMR in H.Jasak's phD thesis, and a report about icoDyMFoam. I am wondering if AMR can be implemented in simpleFOAM as there is no simpleDyMFoam. |

hello,
* You can switch your solution to a transient pimpleDyMFoam case, and run for a few (or more) time step, thus doing mesh adaptation, then switch to simpleFoam, keeping the mesh (just modify controlDict, fvSolution, fvScheme), i.e: 1) run with simpleFoam 2) modify system dir, and run with pimpeDyMFoam from latestTime 3) modify again to come back with simpleFoam * Or modify the solver simpleFoam (not too difficult if you already done this once.)

Thank you olivier.
The first method is really a nice trick . Will let you know my further progress. |
