Default mesh refinement based on previous temperature field

Hi all,

I want to do mesh refinement based on the temperature field in reactingFoam solver. The mesh has to be coarse where the temperature is low, and fine where the temperature is high. This has to be done only once during the start of the simulation.

I looked up dynamic mesh refinement, on damBreak tutorial which does mesh refinement based on alpha.water. I want to do something like this but only once on reactingFoam solver.

Any ideas on how to achieve this ?

Hi,

You can run solver for one step with mesh refinement and then restart it without mesh refinement.
