Compute one physics without changing another

Hi Comsol users,

I am modeling a laminar two-phase flow with some transport of diluted species.

Between each computation, I change some parameters in the transport of diluted species but I do not change anything in the laminar two-phase flow, so only the results from the transport of diluted species may change.

Is there a way to compute only the transport of diluted species physics with the laminar two-phase flow that has been computed previously?

Thanks!
