Elmer 8.2 / 8.3 - mgdynamics solver convergence problem

Dear all, I am working with the usage of mgdynamics solver to simulate magnetic field distribution and eddy currents in the element. Recently I updated Elmer from version 7.0 to 8.3, because of the improvement in calculations speed. Since then around half of my simulations (I conduct a lot of them) ...

Mgdynamics solver does not compile in changed geometry

Hi all, recently one of my students was modeling a zero-Gauss chamber (a place with no external magnetic field). External magnetic field (which was attenuated in the chamber) was modeled via the cylinder with proper boundary conditions. The simulation was working fine when the chamber axis was paral...

Re: Elmerf90 - too big array (?) to compile module

Hello again, I have another problem connected with the previous one. Since I cannot set values of the array as previously (with the usage of DATA structure), I had an idea with declaring every value in the array seprarately. The code fragment looks like this: MODULE interpUtils Use DefUtils Implicit...

Elmerf90 - too big array (?) to compile module

Hello, I am trying to use my own function as a description of magnetic permeability and electric conductivity. Simply said, I generate in Octave array of values and write them into the .f90 file. When I try to compile the module from the created .f90 file I receive a list of errors. They generally l...

Whitney AV Solver:: Boundary tree edges error

helm.sif Hello, I am trying to simulate a Helmholtz-like coils in the earth magnetic field, for its compensation. I created a model of the coils, which are powered by the potential difference on its edges. Flowing current is calculated by Static Current Solver and computes properly. The resulting v...

Re: Mgdynamics solver - lack of convergence.

Thanks you Matthias and Peter very muh for your answers. Firstyly, Matthias, I tried Salome but I had problems with geometry import - I checked online and problem seems to be caused by new Inventor. Anyway I gave up. Later I tried gmsh but due to unusuall shape of the element achieved mesh was... we...

Mgdynamics solver - lack of convergence.

Hello, I'm trying to utilize Elmer for calculations of magnetic flux distribution around some curved wire. I created model of wire in inventor ( 1_zwoj.igs in attached archive). Then i load geometry to Netgen 5.3 (with OCC). After meshing (mesh.gmsh in attached archive) i run elmergrid (14 2 mesh.gm...
