Elmer crash when clicking on boundaries

Hi, I have downloaded Elmer 8.3-98dec6e6 version. The loading of a project works, but when clicking on a boundary for setting the boundary conditions, it does not turn the selected boundary in red color, the "set boundary properties" box opens partially and after a few seconds Elmer crashes and clos...

Re: Magnetodynamic equation

Hi, Yes one can consider that the IBC in Magnetodynamics is a kind of extension of the "surface thickness" in heat transfer. This IBC can be used in high frequency (I don't think it works for the Static Current Solver) since the electromagnetic skin depth is small enough to consider that all the ele...

Re: Magnetodynamic equation

Hi Peter, In Comsol (I am a Comsol user but am very interested in Elmer) the surface relation between E(electric field), Es(source electric field),H(magnetic field), is attached in the IBC_equation.jpg file. As you can understand it would be very useful to have this add in the (2D and 3D) electromag...

Re: Elmer included equations and Postprocessing

Thanks a lot! I'll try this and keep you informed. I submitted a new post concerning the electromagnetics but have no reply until now. Perhaps you have an answer: when working at high frequencies, the electromagnetic skin depth is small compared to the dimensions of the electroconductive bodies. It ...

Magnetodynamic equation

Hi, When working at high frequencies it is very convenient in electromagnetics, as the electromagnetic skin depth is very small compared with the geometric dimensions, to solve only for the surface of the conducting bodies by using the "Impedance Boundary Condition" BC. So it is no more necessary to...

Re: Elmer included equations and Postprocessing

Hi,
Thanks for that! And how can one access the Paraview environment variable PARAVIEW_HOME?
Regards

Re: Elmer included equations and Postprocessing

Thanks a lot! It works now fine! I installed Paraview and see my first Temperature plot results! Just another question: for the moment I open Paraview with the Elmer .vtu file, externally from Elmer. Is it possible to open Paraview directly in the Elmer environment by typing Run/Start Paraview (whic...

Re: ElmerSolver does not work

Dear Matthias, Now it works fine! But I could not run the postproccessing (neither Start ElmerPost nor Start ElmerVTK which gives nothing or a blank window...). Have you an idea why it doesn't work? Is it possible to get more equations (like for instance turbulent flow) than the default included one...

Elmer included equations and Postprocessing

Hi, I am new in Elmer and have it installed recently. I have 2 questions: 1/ After installing Elmer I see that there are a only few equations included(electrostatics,heat equation, Navier-Stockes,etc...). On a youtube tutorial I saw that there are other possible additionnal equations (like turbulent...
