I'm trying to perform a thermal analysis to see how cables affect the conduits and its surroundings. I would like to put currents through the conductor but do not know how to convert ampacity to heat flux. So I tried to set the conductor temperature as 110 deg C. However, it shows that it's not affecting the surroundings because of how it is mated. How do you mate the cables and ducts so it touches the bottom of the conduit without having any interferences? In addition, how do I create the cables so that it touches together and forms a triangle? and then using this to load into the ducts and have the bottom of the triangle touch the bottom of the duct without interferring? 

also, does solidworks allow you to set ur model in an environmental setting. for instance, my model is in room temperature and I want to include this in my analysis showing how room temperature affects the temperature of the cable.

Thanks!
