I'm working on a thermal simulation with a constant temperature heat source. I also applied convection and radiation conditions. I place a body around the product components to represent a volume of air around the device.
To me, it appears that the heat is moving away from the heat source and then moves laterally once the outer surface of the air mass is reached. I would have thought the outer surface of the body would not affect the movement of heat. I might be missing a boundary condition. Is there any recommendations on how to run the simulation differently or maybe comments if the simulation is working as expected?
I have tried making the air mass larger but the simulation doesn't complete for mess errors. I also think that making a larger air mass body won't help because the steady state simulation will run longer as it heats up a larger air volume. I would optimally be able to see the different steps in the simulation but Fusion doesn't have that feature or ability to set a time limit.
