### Re: WhitneyAV 3D coupled current emag of a coil

Hi all, out of curiosity, did anybody check how the mesh looks like before running the simulation? I mean, have a look at the pictures below, it doesn't look good... I suspect this is the reason why the solver is not converging. brokenMesh1.png brokenMesh2.png brokenMesh3.png If you are still intere...

### Re: Problem calculating the magnetic energy of two coils

Hi Peter, Thanks a lot this is very useful information! The feature of having a single body force shared with all bodies that carry current is very nice. I think it would be a good idea to put at least a link of your five coils example in the "Contributed Cases" section. Going back to your previous ...

### Re: Problem calculating the magnetic energy of two coils

Hi! :), any news? From my side I have gone on with further simulations. The impression is that something is not right with how the potential calculated with currStatSolver is passed to the WhitneyAVSolver. Is this keyword correct? electric potential = Equals PotentialA I'm saying this based on the a...

### Re: Problem calculating the magnetic energy of two coils

Ok, so I've implemented the sif with potential as body force. Since this is the fist time that I use the electric potential as body force I have simplified the problem using only one coil (the second coil is treated as air). The sif is as follows: !!------ Skeleton for body section ----- !Body 1 = a...

### Re: Problem calculating the magnetic energy of two coils

Hi Peter, Varname_1, Varnale_2... uh... I didn't see that coming. I'll correct the names as recommended. About coilSolver, though I'd like to use it, the solver is not capable of handling complex structures which is what I'm planning to use once I validate (hopefully...) the solution of this simple ...

### Problem calculating the magnetic energy of two coils

Hi all and happy new year!! :) I'm working on the following problem: I have a system which is represented by two adjacent coils (the surface they enclose lay on the same plane and the coils don't touch each other, see picture below) in free space. adjacent_coils.jpg Each coil carries a known constan...

### Problems with coilSolver

Hi all, I'm trying to solve for the current in a 3D closed coil (see picture below) closed_loop_std_10_turns.jpg Unfortunately the solution that I obtain with coil solver is not plausible (see picture below, a volumetric view of current density magnitude) because in this case current is a solenoidal...

Hi Peter,

indeed, commenting "Calculate Joule heating = True" removes the problem.
