Case: Heatsink which is cooled by a fan.

In fact i have many different flow states (different operation point of the fan)
I am interessted in the transient behaviour of the heatsink.
Therefore i use the chtMultiRegionFoam solver (openfoam v5)

To increase the simulation time i want to do the followinginstead of using the standard transient chtMultiRegionFoam)

1) calculate the different flowfields for the operating points of the fan (steady solution)

2) i use the chtMultiRegionFoam solver in the frozenflow mode

3) i have a temperature critiria. at some specific point the heat sink has a certain temperature. at this temperature i want to increase the power of the fan (changing the presimulated steady state flow field)

my question is: does anyone have an idea of how i should implement my solver? is it possible to have a pointer for the Fluid field variables?somehow like this

if temperature condition 1 is true: U-->U1 (p-->p1...etc)
if condition 2: U-->U2
if condition 3: U-->U3

or is there a better idea to implement my solver?

thx!
