Heat generation along a line in 2d

Post by abasak123 »

Hi,
I have to analyse thermal conduction in two bodies (2d) which are in contact along a line, with internal heat generation at this interface (defined as W/m2). Any idea how this can be solved using the HeatSolver solver (other than defining a thin region at the interface)?

Hi

Just set "Heat Flux" to be the heat generation (W/m) on the 1d line. If the temperature is continuous nothing else is needed. If you have also a temperature jump at the interface this would be more complicated.

Hi Peter,

If I were to model with a temperature jump, how about using "Heat Gap"? I could not find any documentation on this, but it is there in the source code...any idea?

Hello,

If one were to search fem/tests for 'Heat Gap', five sif files will be retrieved. There is a test case named 'Heat Gap' that may be helpful

Dear Rich,

yes I am aware of that example..and I have explored the source code to understand what the keywords of that example mean..I think I have a pretty good idea..but a proper documentation would have been nice.
