Elmer Discussion Forum

Hey guys,

I've uploaded the files to my github and also included a pdf with some guidance to set the simulation and some results.

Just to put a little more wood to the fire. Here is the same example, but using WPotentialSolver. I have simulated a harmonic model with the full coil, using CoilSolver, and half coil, with WSolver. Results from CoilSolver for massive coil is either divergent or VERY off. WSolver is ok, but has ZERO...

Hello all, I was helping a friend with CoilSolver and encoutered a few inconsistensies. First, the only way to get results from Current Density is by using the Body Force without the keyword 'Use Elemental CoilCurrent' in the AVSolver. Other options gave zero for current density and actual current v...

During a visit to an entertainment park, I saw the strategy used by Elmer for gluing different solvers.
Congrats to you all, it is a very elegant solution.

Hello Peter, Thanks for you response. I am reading the data through SaveLine procedure and I am getting the expected results. Actually, using Element = p:2 gets close, but best results is trough increased order elements in the mesh. I haven't checked the simulation time yet. Also, considering the si...

Thanks for the response, Mika.

About the result. Shoudn't B be defined by a linear variation and not a constant value in each element?

Hello all again, I saw that 'Quadratic Approximation' and 'Piola Transform' Keywords are not in the MagnetoDynamics2D solver. But they are changing the results considerably (Ps. I am using higher-order elements from ElmerGrid -increase) Is there a recomendation regarding these? Thanks again for your...

PS. updated my Elmer and this problem with Quadratic approximation is solved.

Also, When I use: Use Piola Transform = Logical True Quadratic Approximation = Logical True The linear system convergence is better, but it haults at the MagnetoDynamicsCalcFields. Simulation stops abruptaly. SingleSolver: Attempting to call solver: 3 SingleSolver: Solver Equation string is: calcfie...

Hello all, I am trying to simulate 2D magnetic flux distribution using higher order elements. I am trying this because I want to simulate a induction furnace applied to thin electrical steel laminations (0.27 mm). My thinking is that second-order elements would reproduce better the induced current i...
