Is it possible to use internal heat sources with a steadystate Thermal Model, using the PDE Toolbox?

The titel already covers the main part of my question.
I have a code that works, if I use a transient model. But when i switch to a steadystate mode, it returns false slolutions.
So i was wondering if it is even possible to use internal heat sources with a steadystate model.

Yes, it is possible to use internal heat sources with a steadystate Thermal Model using the PDE Toolbox. The false solutions you are getting might be a result of setting the boundary conditions or other settings incorrectly.
This page provides two detailed examples demonstrating how the PDE toolbox can be used to obtain the solution to a Steady-State Thermal Model in MATLAB.
I hope this helps!

Thanks for the reply.
You pointed out that setting the boundary conditions or other settings incorrectly might result in false solution. As i said my code works fine in the transient case. In the steadystate case I have the same settings and boundary conditions, except for the model type beeing steadystate.
Do you know if there is a difference in general comparing the settings for both cases? If there are none, my code shouldn't output diferent results.
