Solving only specific cells with interFoam
 

Hi!

I have made a solver which extracts cell IDs based on certain parameters. My entire domain is being tracked by interFoam initially. Once these cells have been identified, I don't want interFoam to track them. I am using another solver for tracking them. I know one way is to modify the volume fraction of those cells to 0 but this poses several issues, the biggest one being that the solver crashes because of sudden change in volume fraction.

Can someone share their views regarding this?

Thanks in advance
