Hello colleagues,

I have a question regarding energy sources. I read through the CFX documentation for this answer and could not find anything explicit to this topic.

I have a box generating 450W which I have created a subdomain to assign this value to a volume.

An older engineer said he uses a rule of thumb that 60% of heat will dissipate through a baseplate which for this case would be 270W. I created a boundary for the bottom of the box and created a total source of 270W to account for this.

My question is this: how do these sources work together? I originally thought that the boundary would override the volume source, but when I have them together the baseplate is heated up a lot. When I only have the boundary the temperatures are a lot more feasible, but it doesn't make the analysis a full model. Is this possible?

Thanks for your time!
