Re: Thermal simulation of PCB
Hello again Matthias. Your help has been trully great, by scaling the coordinates now all the results are in reasonable ranges. As a final question, I'm supossing it only modifies the coordinates and therefore I don't need to change the value of the rest of the constants in the problem (Heat conduct...

Re: Thermal simulation of PCB
Hi mzenker, thanks for your help. For the mseh generation I used Salome, stacking all the layers together and adding a box as CPU. I then made a partition including everything and made groups. Finnally Salome generates the mesh with 1D2D3D Netgen algorithm and I create groups within the mesh and exp...

Thermal simulation of PCB
Hi all. I'm starting to work with Elmer and I've encountered some issues. I'm trying to simulate the thermal behaviour of a PCB board with a CPU that generates the heat. I set the case as I think it's correct but the results are not satisfactory (The CPU reaches 10^5 K and the rest of the board rema...
