Mapfields with two different turbulence models

AirS · November 4, 2009, 11:23

Dear Foamers,
I've got two meshes (coarse/fine) and I use a different turbulence model for both of them. Basically, I was wondering if it was possible to use Mapfields in order to import results from coarse mesh as an initial condition for the fine mesh which uses another turbulence model.
Thanks!

The initial conditions on the turbulent variables do not matter a lot. As long the the velocity field is perturbed, turbulence will develop and you should be able to obtain statistics.
