New SimScale user here - so far, I’m really impressed by the usability of the UI. I’ve just started my first project to evaluate the platform for use in future product design at my company.
Project basics: The design has a single heat source (a switching power supply IC), a PCB, and an aluminum heatsink. I’m modeling the heatsink as a chunk of Aluminum (solid) as a “heat spreader.” Eventually, I’ll replace it with a more realistic model including fins. The switcher acts as a heat source of 3.75W at the specific operating point I’m concerned about. I want to estimate the steady-state temperature field of the switcher, PCB, and heatsink.
I’ve imported a simple STEP model of the product and I believe I have the meshes correctly defined. I also followed the heatsink tutorial design step-by-step to get to the point of a converged simulation. However, when looking at the results, it seems like there is no heat conduction between the three regions of the simulation - the heatsink, PCB, or switcher.
I attempted to try and add Interfaces between the components specifically, but this caused Errors when executing the simulation.
Would anyone be willing to take a quick look at my project and see if there is anything obviously wrong?
The project link is here: https://www.simscale.com/projects/koolscooby/0301-02-0001b_1/
The appropriate CAD model is “Export B” and “Mesh 3.” I’ve executed the simulation successfully a few times, but the results don’t seem to be meaningful.
Thanks in advance and I appreciate your expertise!
