### Introduction We are creating an example Jupyter notebook for demostrating the usefullness of Elmerfem as backend in circuit simulations: https://github.com/ER-solutions/CaseStudies/tree/main/ElmerNotebook ### Problem: Coil solver gives strange results when run...
The main application for the y-axis and w based local coordinate system is the stranded homogenization model where the homogenization parameters are oriented using the RotM transformation. The RotM transformation...
Original idea by @raback https://github.com/ElmerCSC/elmerfem/issues/429#issuecomment-1844918452 So the idea would be to refactor `RotM` functionality and its application to tensor transformation. Use a test case, for example [this](https://github.com/ElmerCSC/elmerfem/blob/devel/fem/tests/circuits_harmonic_stranded_homogenization/sif/2241.sif) and refactor the...
Sometimes local coordinate system is needed in coil formulations. Currently we can define that by using the thickness direction and height direction in rectangular coils. If those are not available...
Assuming we know edge element dofs we can calculate values at integration points: $a_\mathrm{ip}=R_\mathrm{w} a_\mathrm{dofs}$ or $a_\mathrm{ip}^T=a_\mathrm{dofs} R_\mathrm{w}^T$ Explicitly in code: `a_ip(1:3) = MATMUL(a_dofs(nd-np), wbasis(nd-np, 1:3))` Assuming we know values...
Homogenization for harmonic 3D stranded coils [exists](https://github.com/ElmerCSC/elmerfem/blob/60e66a71eaf845149cb4876d1fc279d311bdcb6d/fem/src/modules/MagnetoDynamics/WhitneyAVHarmonicSolver.F90#L1490), but the loss distribution processing is not yet implemented. In principle, we could already replace the homogenized "sigma" in [material parameters](https://github.com/ElmerCSC/elmerfem/blob/60e66a71eaf845149cb4876d1fc279d311bdcb6d/fem/tests/circuits_harmonic_stranded_homogenization/sif/2241.sif#L157) and get...
I have added a case that is the same as `circuits_transient_massive` but steady state: https://github.com/ElmerCSC/elmerfem/tree/circuits_steady/fem/tests/circuits_steady_massive Maybe I did something wrong, but seems that it does not converge.
Hello! Thanks for the great project! I tried to build (compiles) and run tests. I got an error: ``` ➜ pyplot-fortran git:(master) fpm build --profile release pyplot_module.F90 done. libpyplot-fortran.a done....
I did some review and documentation for our electrodynamic models (AV). I think I also found a bug in MagnetoDynamics2D. Let me know if this can be merged.
Here we add the general formulation for calculating the flux linkage using the coenergy method. In order to calculate the flux linkage of all the components, one must set to...
