Hello. First I will thank the people who put their efforts into the Elmer program and this forum. Very cool.
I trying to estimate the resistance and heat generation in a somehow complex geometry. I have the basis analysis running and can display distibution of "Potential" and "Joule.Heating". I have these questions:
1. Is it possible to see somewhere the amount of current passing through each boundary with prescribed voltage condition?
2. Is it possible to display the distribution of current density [A/m2] at the boundary surfaces?
3. The solver log says: "StatCurrentSolve: Total Heating Power : 1.17374053293362881E-003"
- Working with SI units, is this then the integral of ohmic heat over the Body in W?
Thanks for your comments and feedback.

Re: Static Current Conduction
Hi
1) Yes. Two alternatives. Look at discussion on computing heat flux and just replace Temperature -> Potential and Heat Conductivity with Electric Conductivity. In short
3) Yes, there should be even an estimate of the resistance using R=U^2/P. See StatCurrent.src in line ~450

- Calculate Loads + SaveScalars solver & boundary sum (more accurate)
- SaveScalars solver & diffusive flux

Thank you very much for the quick answer. I will try your sugestions.
