Hello, everyone
Recently I was doing a heat dissipation model and set my initial temperature model according to the initial temperature model of free_surface-prm. At the same time, I also set three sets of controls, two of which were at different positions of heat sources, respectively above and below the mantle (the function expression of the initial temperature model of these two groups: sqrt((x-0.95e6)^2 + (y-0.8e6)^2) < 100e3? 5000.0:1300.0; sqrt((x-0.95e6)^2 + (y-0.2e6)^2) < 100e3? 5000.0:1300.0). The last group is the case of no heat source, and its initial temperature model is set as shown in the figure below.
However, there are some problems in the statistical graph of the final mean temperature. The curves of the three models with the heat source are lower than the curves without the heat source for a long time. It’s like a cup of hot water that cools faster. This seems reasonable if the temperature without a heat source is cooler than the temperature with a heat source most of the time. I guess it’s probably a problem with my boundary conditions or the initial temperature model for the model without the heat source. Where should I start if I want to change it?
Welcome the experts’ correction
