Adaptive mesh refinement using simpleFOAM
 
How to implement dynamics adaptive mesh refinement using simpleFOAM.?

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.

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.)

Regards,
olivier

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