Hello everyone, I have a question regarding the conceptual understanding of my model. I am currently simulating conductive heat transport in the subsurface, which is controlled by Dirichlet boundary conditions with fixed temperature values and by thermal conductivity. In addition, I have implemented ENERGY_RATE SCALED_ENERGY_RATE VOLUME in order to assign radiogenic heat production to the individual stratigraphic units over their entire volume.

I would now like to determine the point in time at which quasi-stationary conditions are established. However, is such a state even attainable? I am assuming that the model boundaries are adiabatic, meaning that the heat introduced into the system by radiogenic heat production cannot be dissipated. Consequently, the temperatures would have to increase continuously over time.

Is there an error in my reasoning? If not, how can this issue be resolved?

Best regards
