Elmer Discussion Forum

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

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"....

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 ...

Hi

Yes, indeed.
Works.
Thank you and cheers

Hi xiejinzhi

I just came across your post because I'm dealing with a similar question.
Does the B vector field look reasonable?

Cheers

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...

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...

I was searching the forum regarding the use of " Physical groups " from gmsh in ElmerGUI. It was already discussed here: [1] https://www.elmerfem.org/forum/viewtopic.php?p=23437&hilit=Physical+Curve#p23437 [2] https://www.elmerfem.org/forum/viewtopic.php?p=24515&hilit=Physical+Curv...

Hi Peter Right, thank you for the explanation. Only the normal component, understood. But just to close the first loop, let me ask again what did you mean with the "nodal weight" ?: If you want to know the charge distribution then divide this by the nodal weight. See test case "Weight...

Hi Peter Thx for your response. Ah yes, of course, Flux1 and Flux2 are in Cartesian components. Thx. To get the tangential component on an insulator surface, I would simple do Ft = sqrt( E1**2 + E2**2 ) - Fn with the extracted data from SaveLine solver. Do you think, this is not accurate enough? In ...
