Electromagnetic vector field solver

Hi Elmer, What is the status of the electromagnetic field solver? I remember a post circa November, 2013 to the effect that there is an undocumented solver in the development branch and that a lot of work was going into it at that time. How can I learn more about suitability to solve some vector E&a...

Re: Thermal stress in 2D

Hi,

To sum up and for the benefit of some future novice, I've attached mesh, sif, and results for a square with three edges fixed under 100C (figure a) or 200C (figure b) of thermal stress. The behavior is physical. This should help get someone get started with thermal stresses.

Thanks again.

John

Re: Thermal stress in 2D

Great stuff! Thanks, Anil. Thanks, Peter. Per Anil, I went back to Salome (7.5.1) and was able to make a geometry/mesh that worked fine with that same SIF in Elmer. So the workflow is fixed. THANKS. Have begun to reproduce the nice panel Anil made. Peter, re: need to fix at least 3 DOFs, understood....

Re: Thermal stress in 2D

Hi Matthias, Thanks for the comments. I indeed did not specify boundary condition because the Models Manual states (right after the sentence you quoted) The default boundary condition is the natural boundary condition which implies that ~g = 0. So, I made this explicit by adding to my sif: Boundary ...

Thermal stress in 2D

Hi, I'm trying to simulate thermal stress/strain in a simple 2D system: A top block (called "rib") affixed to a bottom block (called "substrate"). The reference (stress-free) temperature of the rib is 400K and of the substrate 300K. The system is at T=300K. I use statements like ...

Conformal mesh for magnetostatic calculation?

Hi,
Do I need to use conformal meshing for magnetostatics?

For example, consider a current-carrying wire surrounded by an air/vacuum box. My workflow is FreeCAD->NetGen->Elmer to generate two bodies in Elmer. Do the two meshes have to be conformal in order to run magnetostatics?

TIA

Looking for consultant for electromagnet problem

I'm looking for consulting support. Should be able to set up a static electromagnet simulation. Nonlinear B-H is preferred but not must-have. I provide the geometry. Deliverables: (1) Elmer model. (2) Short written instruction doc explains how to use the model to extract B-field for given current. P...
