I have the following problem: I am trying to simulate the cooling of some electronic components and the way the materials they are made of influence the speed and efficiency of the cooling process.
So far I have the following:
1. The assembly in the attachment.
2. Defined the capacitors as made of aluminum and the PCB as made of FR-4.
3. Defined a fan for the circular lid and boundary conditions for the exit fins.
4. Succesfully ran flow simulation.
What I want to do now is some sort of animation: lets say that the components start out at 85'C and I want to see how the air circulating around the components cools them in time (and in what time). Then, change the material and/or placement of the components and rerun again.
For this I'd like to see a cut plot of the components and see the way they are cooled from the outside to the inside.
It there any way to do this?
Because if I define the components as heat sources then they are kept at constant temperature (as defined) and you cannot see the cooling, but rather, them heating the air around it. I want the exact opposite: the air at constant temperature and the solid materials varying in temperature.
I tried to define the initial temperature of solid materials to 85'C, however, when playing animations it seems to start where the results have converged (i.e. the solids already have been cooled).
Thanks in advance for any help you can give me!
