Re: Surface as a body in 3D

Hi raback, thanks a lot, this is exactly what I was looking for. Indeed it was under my nose all the time in ElmerGUI! By clicking on the surface whilst defining the boundary conditions you can just click on "Use as body" and it will automatically appear as a body with the ID of the surfac...

Re: Surface as a body in 3D

Thanks mzenker, I have also posted in the thread you linked in case some developers see it! For now I will try and mesh a finite-thickness layer and look at the result.

Re: Elmer version 8.2. is published

Hi all,
I am going to try and revive this old post. I have recently opened a thread asking about 2D/3D meshes in static electric current solver (viewtopic.php?f=7&t=5976), are there any plans to add this as it was done in the heat solver?

Thanks!

Re: Surface as a body in 3D

Thanks, I thought so, I will try with a thin layer. However, I know that other FEM software allows to define a surface as a body and therefore give it a different material. Do you know if this is doable in elmer? I use gmsh to define geometry and mesh but I don't know how to define a surface as a se...

Re: Surface as a body in 3D

Sorry, my mistake. The current is flowing along the surface (I amended the original post).

Surface as a body in 3D

Hi all, I am still a novice in Elmer and FEM in general and I have a fundamental question. I need to simulate current flowing along a surface surrounded by dielectrics (two different fro top and bottom). I need the problem to be in three dimensions since I want to map the electric field in space and...

Re: Problem with tutorial 14

I found a solution to the problem. It was actually already been seen but hidden in this post: http://www.elmerfem.org/forum/viewtopic.php?f=3&t=4382 The problem was bug in the 8.2 version, installing the latest nightly build soled the issue, now I get a sensible value for the capacitance and the...

Re: ElmerGUI Tutorial 5 (Electrostatics Capacitance)

I don't know if it is too late but I had the same problem. The solution is to give a value to the field "capacitance body" in the BC tab. This should be an index which then makes up the (i,j)'s of the capacitance matrix.

Problem with tutorial 14

Hi all, I am new to this forum as I am new to Elmer. I have been using it for a while now to perform some linear elasticity simultaneous and recently I am trying to simulate electrostatics. I was following the tutorial 14 (Electrostatic equation – Capacitance of perforated plate) but the result is w...
