Basic heat definition question

Hi,
I have been doing conjugate heat transfer problems on cfx and I have been defining heat generation on my pipes using the subdomain feature. I select all the pipes in the subdomain and specify source as 1000 W/m3. My question is, do all the pipes get 1000 W/m3 or does 1000W/m3 get divided equally among the pipes which I have selected. I think it gets 1000W/m3 each, but I just want to make sure. Thanks for reading. |

Make sure you understand the unit - it is W/m^3. So it is a heat source per unit volume, which means whatever you select will get the same heat source per unit volume applied all over it. It does not get "split up" - that is not meaningful for that unit.
