Re: Edge degrees of freedom
Hi Peter Thanks for the help! On your advice, I tried keyword: Linear System Remove Zeros = Logical True In WhitneyAVHarmonicSolver I didn't notice any difference whether the keyword is True or False. On the other hand, in WhitneyAVSolver the simulation diverges when the keyword is True. I see that ...

Re: Edge degrees of freedom
Thanks for the help Mika! I was able to implement the weak AT-formulation shown in the paper by Albertz and Henneberger "Calculation of 3D Eddy Current Fields Using Both Electric and Magnetic Vector Potential in Conducting Regions", IEEE Trans. Magn. I used the following approach: Variable...

BodyForce - edgeDOFs
hi, Can BodyForce be specified in Elmer using edge elements? So, just as the Boundary condition is specified in the form of edgeDOFs in SIF-file, the edgeDOFs for BodyForce would be specified in the SIF file in the same way. I guess it would then look like this: Body Force 1 Name = "edgeDOFs...

Re: Edge degrees of freedom
Thanks for the reply Mika! To be more precise, this is the AT weak formulation shown in the paper by Albertz and Henneberger "Calculation of 3D Eddy Current Fields Using Both Electric and Magnetic Vector Potential in Conducting Regions", IEEE Trans. Magn. In this paper, both A and T potent...

Edge degrees of freedom
Hi Is it possible to use a variable that has more than one degrees of freedom per edge? By this I do not mean edge basic functions of the second degree. For example, is it possible to use a weak formulation containing E and H vector fields (where E represents the electric field vector and H represen...

WhitneyAVHarmonic - low-frequency homogenization
Hi, I see that in MagnetoDynamics module low-frequency and wide-frequency models are implemented for enabling homogenization of laminated stack. What is with post-processing? I can not find any piece of code in SUBROUTINE MagnetoDynamicsCalcFields that takes into account eventually homogenized field...

Re: Improved visualization of discontinuous fields
Hi Peter, Thanks for response :) I installed binary one year ago. So, it is offical version from May, 2017. I have tried to simulate another test case without circuit simulator and it worked fine. I thought maybe the problem is in Paraview visualization of simulation that uses second-order edge elem...

Re: Improved visualization of discontinuous fields
Hi Peter, I am trying to simulate test case circuits_harmonic_massive (1962.sif in your github repository) with quadratic approximation and results drastically differ (in Paraview) from the expected results that I have been gotten after simulation with first order edge elements. Here is the sif file...

Coupling of models
Hi, I use two models to solve my physical problem, i.e. I am solvimg my problem partially in 3D and partially in 2D which is projection of 3D geometry in x-y plane. In other words, one model is upon 2D geometry, and second model is upon 3D geometry which is actually the 2D geometry extruded in z-dir...

Re: WhitneyAVHarmonic - edge elements in 2D mesh
Peter and Mika thank you for your answers. It is good to know this.
Thanks for reference on EdgeFEInterpolationTest.F90, it is really useful.
