Elmer Discussion Forum

Hello, I'm calculating the self inductance of a coil in a 2D setup by three methods (to compare them). First method is using the energy stored in the problem space which is reported by Elmer on the command line output (and in the save scalars output file). Then use L = (2 * Stored Magnetic Field Ene...

Hello Tobias,

Have a look at viewtopic.php?f=7&t=7151&p=23142#p23142. It is more or less the same question as you have here.

If that post doesn't answer your question, I'll try to answer any follow-up questions you may have.

Best,

James

Hi Peter, Thanks for looking through it. I'm glad you approve. I'll try to add the pieces that are still missing over time. It all started because I wanted to compile the small change you made to calc fields to split up the magnetic field energy from the electric field energy. I'm planning to simula...

I have written a build method for Elmer which includes a number of the optional packages.

It seems well to point out that the fastest way to get going with Elmer is to use a pre-compiled binary or the official virtual machine.

Hi Peter,

Many thanks for adding that in. Much more professional than me hacking away at it. No Fortran for me since my PhD days.

I'll download the nightly build from 24/9/20 tomorrow and fire it up.

Hi Peter, Many thanks for replying. You obviously put a lot of your time into working on and supporting ELMER. I am very grateful. Presuming I make the required addition to the source file to list the parts of the energy separately. Would I then compile the source with elmerf90 as Pavel did with the...

I am attempting to evaluate the inductance of a magnetic component using simulated with MagetoDynamics 2D and the Circuits and Dynamics modules. One approach on this forum is to use the (Electro)Magnetic Field Energy which is output from MagnetoDynamics 2D on the console as the solver runs. However,...

Hi Peter, Many thanks for taking the time to answer. If I could trespass on your time a little further, I have a few follow-up questions: 1. If the MgDyn2d is used with an axis-symmetric problem does what you've said still apply? Is the quasi-3d aspect of the 2d problem built into the revolution of ...

Hello, I'm modelling some magnetic components for power electronics applications in MgDyn2D using cartesian coordinates (no symmetry). My test case is a 'coil' modelled as a current density flowing parallel to the z axis in two regions, one into, and one out of, the page. There is a ferrite core mod...
