Nonlinear heat generation

hello!

Is it possible to have a heat source be both temperature and thermal conductivity dependent? i have been slowly integrating temperature dependence and verifying it is behaving as i expect it to. however i would like to add this dependence to my heat generation, something like

heat source = 100k/(3T)

Thanks!

If I don't miss anything, that should not be more difficult than typing it in! heat source = 100 * k/3/T with k defined either as a parameter, either by ht.kxx if you use the heat transfer physics (isotropic), either referring to the material definition : mat1.def.k_iso if you have defined it in the materials section. Or k may be defined by a more elaborate expression that may be dependent on T (or from another equation that you would solve for), in such case just type it in! So if you made it with including T, adding dependence on conductivity should be easy. Good luck! Eric Favre
