Hei, I try to utilize mesh refinement options of Elmer in a MagnetoDynamics2D model with mortar BC and rotating mesh part. The attempt to increase mesh level by Mesh Levels = 2 in the Simulation section results in segmentation fault ELMER SOLVER (v 7.0) STARTED AT: 2014/07/12 20:24:33 MAIN: MAIN: ==...

Hello, Here is a tutorial/workflow example of application of Elmer in simulations of electrical machines. https://dl.dropboxusercontent.com/u/542224/ElmerFEM_EM_V1.0.pdf The project files are here. https://dl.dropboxusercontent.com/u/542224/ElmerFiles.zip This tutorial is not yet complete, but it ca...

Hello, I have a question considering BSolver in MagnetoDynamics2D. Does it use keywords for nonlinear solver? In my case (see .sif below) no matter which "Nonlinear Solver Convergence Tolerance" I specify, BSolver always performs only 2 iterations and then goes to the next timestep. I ask ...

Hello, Here is a postprocessing video of a PMSM 2D MagDyn model. http://youtu.be/1gIOrbyePo0 In the center of the airgap at several timesteps appear artifacts which spoil the simulation. First at time 4 s. And most apparent at 24 s. These points are at every pi/2 along the airgap. I’ve got the follo...
