Finding volume while model is running

Hello All,
I am attempting to build a model using the heat transfer module in which the total power is constant, but as time progresses the volume that the power is spread over is changed however I can not figure out how to get the volume of a domain during the simulation.
If you could not tell from my question I am a beginner and can not seem to find this is the documentation.
Any help would be appreciated.
Thank you,
John Haase

Hi
the volume of a domain is simply defining a "integration operator" on the volume and then define a variable
Vol = intop1(1)
Or you might use the formula "intop1(1)" directly this means integration over the selected domains of 1*dx*dy*dz, the "dx"dy*dz are implicit.

Good luck

Ivar,
I am still having problems with this I define the integration over domain 2 as intop1 and then create a parameter called Volume_LAZ with a value of intop1(1) and then create a heat source with a volume of 4000 [W] / Volume_LAZ and yet there is still a problem.
Any suggestions would be appreciated.
