Hi, I have a ring conductor in 2D axisymmetric (a turn with a hole for the water cooling). I have a sinusoidal current at 11kHz. I solved the problem to get the distribution of the specific power with the function assempde. Now I want to solve the heat equation to see the distribution and the trend in time of the temperature. I have an FE mesh and the power is given in the center of each triangle. On external boundary I have convection and radiation and on the internal only convection. How can I deal with this problem? Thank you

Take a look at this example:

Hi Bill, In the example you have mentioned above (i.e. Nonlinear Heat Transfer In a Thin Plate), is there any way in Matlab to assign different heat transfer coefficients to different edges? Thanks for you help.
