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...

Re: problems with MGDynamicsCalc

Hi Peter,

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

Thanks for your help!

problems with MGDynamicsCalc

Hi all, I'm having a problem MGDynamicsCalc solver, given a specific current injected in a simple 3D coil (1 turn surrounded by air) I'm trying to calculate its magnetic energy. The current solver seems to work (I have only checked the statCurrent solver output, btw is there a different way to check...

Re: magnetostatic with mesh morphing

Hi Alex,

You can, for example, split the zip file in two or more smaller files directly with winzip. Or decrease mesh density.

Regards,

Re: Beginner in using Elmer

Hi Charlezyi, Another option to keep an eye on for 1D modeling and simulation is openmodelica https://www.openmodelica.org Here you get the bonus of 3D animation included in the simulation (some configuration required...) In your case animation might not be a decision maker since your projectile can...
