Static Current Conduction question
Posted: 21 May 2024, 14:25
Hello,
This is my very first try with Elmer and this kind of simulations at all. My try is based on this tutorial.
https://www.youtube.com/watch?v=hNHTwpegFBw
My setup consists of V shaped PCB trace with a source pad on the sharp edge and two sink pads at the ends of the two branches.
And it aims to visualise the potential drop, volume current and joule heating.
At the source pad I did applied Dirichlet boundary condition with a potential value of 5V.
My sink pads has equal arias of .895mm^2. I applied Neumann BC's.
So at pad A I applied 1A current equal to current density value of -1117318 and to pad B 4A equal to CD of -4469273
Everything seem to work, but my output shows too much of a voltage drop. Pad A potential value is 1.2 and pad B is -8.
It should be a stupid mistake that I am making somewhere, can anyone give an advice?
I am also not abled to find any examples on Static Current Conduction model except some documentation here https://www.nic.funet.fi/index/elmer/do ... Manual.pdf which I don’t fully understand.
Is there a good place to start learning that?
I am attaching my project.

Thanks in advance!
