### resistance and power dissipation from StatCurrentSolver

Posted:

**07 May 2017, 02:30**Hi all,

Recently I've been working with the StatCurrentSolver and I've found that when you use "Current Control" (current fixed at Ic) the solver outputs the dissipated power as a function of the potential inposed on BC insead of power dissipated by Ic.

In my simulation (see results below) I've set Ic=10A but the "Total Heating Power" is referred to "Total Current" (2715A) which is a consequence of the BC set in the sif file. Of course, you can use the control scaling to obtain the righ amount of power but still, I would have though I would be getting a straight answer.
Can I access and manipulate those variables ("Total Heating Power", "Total Current", ....) via sif file? Can I save them in a file?

Any help would be much appreciated,

Best regards,

Marco

Code: Select all

```
Elmer solver output:
StatCurrentSolve: Total Heating Power : 149.31834149734826
StatCurrentSolve: Effective Resistance : 2.0258730238131670E-005
StatCurrentSolve: Total Volume : 2.0165367700452461E-004
StatCurrentSolve: Total Current : 2714.8789363154228
StatCurrentSolve: Control Scaling : 3.6834054978421220E-003
