Elmer Discussion Forum

Hello Peter, Thank for the response. The mesh came from converting triangle mesh to elmer mesh (FEMM to Elmer FEM). I am trying to create a tutorial to add to elmer-elmag repository. This is discussed here: https://github.com/gforti84/ElmerFiles/tree/main/share_1 I've also added more save line examp...

Hello all, I am trying to use saveline in a simulation, but I've been having issues. The simulation is from a FEMM to Elmer procedure I am trying to create. More information here: https://www.elmerfem.org/forum/viewtopic.php?t=8094 The results from the saveline for this case is very, very, weird. I'...

Ok. Thanks Also, i could not figure a way to work with 'Coordinate Transformation' in SaveData procedure. Coordinate Transformation = String "cartesian to cylindrical" Coordinate Transformation Use Degrees = Logical True Polyline Coordinates(2,2) = 0.010738 0.0 0.010738 180.0 Polyline Divi...

Hello Kevin,

I've tried removing the BC, and other scenarios. But got the same following results in the last simulated step. When I run the case as posted, the results is as shown below:

Thanks for the response. I could not argue with that. I've made this case based on other examples, of course. These includes: - https://www.researchgate.net/publication/275890336_FEM_Modeling_of_PMSMs_Using_Elmer - https://github.com/ElmerCSC/elmerfem/blob/devel/fem/tests/DisContBoundaryDoubleMortar...

Hello all, I wanted to create a example case of the use of FEMM / Triangle to create the input mesh for simulation of electrical machines. But, before submiting to elmer-elmag folder, I wish for help in some points. First: I could not use the 'Discontinuous Boundary = Logical True' directly, the sim...

Hello Peter,

I was trying to create a simple case for this test, but encountered some problems. Please see the git folder:
https://github.com/gforti84/ElmerFiles/ ... in/debug_6

Just added another case folder: https://github.com/gforti84/ElmerFiles/tree/main/debug_5 Simulation time is similar now, and results are close. Now it is time to try this solution on a real case. As soon as I have results for a more realistic case I can share it in elmer-elmag. Thanks for all the he...

Hello all,

Just for the record, the result of magnetic flux along a line, defined as illustrated in the figure below, shows good agreement with commercial software result.

Hello developers, I'm working with anisotropy of magnetic core's permeability. For the definition of non-linear material, the solution is to use reluctivity function. It works fine, just need to tune the problem the get a faster solution. On this sense, is it possible to implement the reluctivity fu...
