I am using the PDE Toolbox, thermal model. I am interested in knowing the heat flux on a given face of my 3D geometry.
I tried to use EvaluateHeatFlux first, but it looks unsuitable for evaluations on a plane of a 3d geometry, unless some thickness is also provided (I might be wrong, please correct me).
Then I tried to use EvaluateHeatRate on the target face as follows:
Qn = evaluateHeatRate(thermalresults,'Face',2);
My question is: what is exactly the difference between heat flux and heat rate? What is the unit of measure of the heat rate according to matlab PDE?
I thought it represented the Watts emitted by the face, therefore to get the heatflux I just had to divide it by the surface area, but it returns weird results.
Can anyone help me please?
