rerun with same flow field, different fluid props

Tim

Hi,

I have simulated the flow of a fluid through a domain with heat transfer. I want to rerun the simulation, but with a different thermal conductivity for the fluid, with all other variables remaining constant (including the flow field). Since the flow field is not effected by the temperature, is there a way that I can rerun the simulation, but not solve for the flow field, only for the temperature, and using the flow field from the previous run?

Any help would be appreciated.
