Accelerate chtMultiRegionSimpleFOAM with local time step
 

Hello Foam Expert,

I am thinking to accelerate chtMultiRegionSimpleFOAM with using localEuler. First step I tried is to use chtMultiRegionFoam with using time scheme localEuler. However, it doesn't work since it need to introduce setrDeltaT.

My question is to make setrDeltaT for local time step, should I use chtMultiRegionSimpleFOAM steay-state solver with add time term. Or I need to change change chtMultiRegionFoam unsteady solver. The problem is I checked the chtMultiRegionFoam solver, it quite different from steay chtMultiRegionSimpleFOAM solver. I am not sure it could be work with localEuler time step.

Cheers,
