hi!i'm new at comsol...i have a cable with insulation and i use both ac electromagnetics and heat transfer modules.What i would like to know is how the '' Qav_qa'' is calculated in the program?by which equation?And when i put it as entrance at the heat transfer module the value that it takes is the average in the volume of the cable?because it does not equal to i^2*r.(there is current only in the insultion).

Hi
I do believe (from the variable name) that you are in v3.5a. THe Q heat flow is the averaged one, in "QA" application mode. THe best is to check the doc (index it and search for your variable name). Then you can look at the "physics" subdomain equations" where you should find this variable and the related equations inside the COMSOL GUI

Good luck
