Re: Elmer for high-frequency circuits in MHz to GHz
Hi Peter I just came across this post since I'm modifying the test case "mgdyn_wave_td" for a coaxial wave guide. https://www.elmerfem.org/forum/viewtopic.php?t=8319 Is there any documentation already available for this solver? Or can you tell me, how I can define the port impedance to mat...

Re: Coaxial wave guide
Thx for your reply. It helped me make progress and it's looking quite good already. Just to ensure everything is covered (for others facing similar issues): Perfect Electric Conductor BC: BC for perfect electric conductor is a = real 0.0 a {e} = real 0 Input Port Definition: As suggested in your res...

Coaxial wave guide
Hi I would like to adapt the test case "mgdyn_wave_td" from a rectangular to a coaxial wave guide . Therefore I have following questions: Perfect Electric Conductor BC: What is the Elmer definition for a perfect electric conductor (n x E = 0) boundary condition? From the test case I unders...

Re: Vector field decomposed in tang and normal component
Hi Peter
Thank you for your reply.
Hmm, ok.
Do you know how to save the normal vectors from Elmer into the same .vtu file ? Is this even possible ? Then I can proceed as you suggested.
Thank you very much.
Cheers

View Factor Fij
Hi For a simple example I'm comparing the numeric view factor calculated by Elmer with the analytical solution. Here I'm considering the following two surfaces: Fij.png If running "ViewFactors.F90" over cmd, the dF_i->j and dF_j->i are stored in a separate file "ViewFactors.dat"....

Vector field decomposed in tang and normal component
Hi all Using Paraview, I would like to split the 2D vector field along the edge of two materials in its tangential and normal components. In other words: I'm interested in the scalar value of the projection of the 2D vector field onto the tangential edge vector. The normal and tangential vectors on ...

Re: [MgDynHarmonic,SaveScaler]current in body force
Hi xiejinzhi
I just came across your post because I'm dealing with a similar question.
Does the B vector field look reasonable?
Cheers

Re: make use of Physical groups from Gmsh
Hi and thx for your prompt respond. Yes, indeed. If I 1. define in gmsh two additional Physical Groups (here surfaces) for the two bodies like: ############################################## Physical Curve("grd", 86) = {75, 74, 73, 72}; //+ Physical Curve("parFlux", 87) = {76, 63...

Re: make use of Physical groups from Gmsh
Hi and thx for you quick response. Currently I'm using Gmsh 4.11.1 (Build date: 20221221) and Elmer v9.0 compiled today 16. of Oct. 23. The procedure I'm using is as follows: 1. Definition of "Physical Curve" in gmsh 2. Generate mesh (order 2) 3. File -> export -> ".msh" -> Versi...
