Thank you. I`ll do some tests with the mesh quality.

As per my solution for the anisotropic BH curve (the reluctivity function). Is there room for improvements?

Thank you for your response.

Is there anything that I can do? I am not very good to go into the FEM formulation, I am more of a user.

Hello fellows, I have some new and updated case files and results. I got better results using input voltage supply and messing a little with the solvers, also the reluctivity function. I would like to know if it is possible to improve simulation time for the anisotropic case, it is significantly lon...

Hello all, Does anyone here have experience with simulation of anisotropic non linear BH curve? I tried a simple simulation using an arbitrary transformer geometry and the results are unstable. The same simulation with isotropic material gives good results in comparison with a commercial software. W...

I usually run Elmer on Linux, but I also have a notebook with Windows. The problem that occurs on Windows does not happen on Linux. I tried installing the version from the site: https://www.nic.funet.fi/pub/sci/physics/elmer/bin/windows/ Its currently the following build: Version: 9.0 (Rev: Release,...

Hello all, Been having problem using Elmer in Windows. Installed the version from the site: https://www.nic.funet.fi/pub/sci/physics/elmer/bin/windows/ Same case which I solve fine in Linux is giving the following error: Program received signal SIGSEGV: Segmentation fault - invalid memory reference....

Hello Peter, I realized a simple simulation to compare the results from FEMM and Elmer FEM. I've compared the circuit results and loss calculations (both with my script). For FEMM, the loss is calculated with the file: trafo_aniso_lin.m (matlab) For Elmer, the loss is calculated with the solver Outp...

Hello Peter and Rich, Thank you very much for this help and provided solution. I tested two cases here and got excellent results. Actually, I had a surprise as it worked beyond what I was expecting. As illustrated in the attached images, FEMM defines circuits differently from what elmer does. We can...

Hey guys....just wanted to share my experience with Arch. Actually a Arch based distro with easy install, EndeavourOS. So, here we are again. From my last procedure, I just want to add the packages dependencies (which is something I would like the very good fellows of CSC to evaluate for other distr...
