Hi everyone, I am trying to run the examples provided here: https://github.com/ElmerCSC/elmer-elmag/tree/main/PermanentMagnetMachine2D I get the following errors trying to run case.sif ELMER SOLVER (v 9.0) STARTED AT: 2024/05/10 10:35:09 ParCommInit: Initialize #PEs: 1 MAIN: MAIN: ==================...

I was searching for an explanation of the Galerkin Projector in the Elmersolver-Manual. Unfortunately it is not mentioned there. But searching the Forum led to some success and valuable insights ;) The source-post of the quote below can be found here: http://www.elmerfem.org/forum/viewtopic.php?p=17...

Hi Kevin, Thank you very much! Could you please explain why it must be the Anti Rotational Projector? As I understood so far, the Anti is used when you want to project the solution multiplied by -1. As this is the full model and no symmetry projectors are used how does this led to the solution? Is t...

Hi everyone, I run in the following Error while trying to conduct the simulation.

Here are all the motormodels:

Hi, I implemented the full-model, the half-model using periodic BC and the quarter-model using anti-periodic BC of a 4-pole motor. No load is applied. See the overview of the models below. overview_motormodels.png To simulate the torque I used the component approach. The deviations of the cogging to...

I would be very thankful if somebody could have a look at my case and answer my three questions in the post above.

The names of the scalar values are: Variables in columns of matrix: 1: res: eddy current power 2: res: electromagnetic field energy 3: component 1: res: magnetic force 1 4: component 1: res: magnetic force 2 5: component 1: res: magnetic force 3 6: component 1: res: magnetic torque The output of the...

An overview of the full_Motormodel geometry is show below. screenshot_geometry_overview_of_full_Motormodel.png The difference between the two half motor models is how I applied the Mortar BC. In my first approach I merged all subfaces of the cut into two separate faces screenshot_2MortarFaces_motor_...

Hi, I highly appreciate, if someone could have a look at the following corrected files and give me hints on my questions below. ( I had to split up my message into separate posts, because i can only upload three files per post...) I figured out, that the files I provided in my initial post are diffi...
