Elmer Discussion Forum

The link was enlightening. Well I'm glad Elmer seems to be able to take care of a surface charge density that varies with location on an arbitrary surface. I am now going to study the tutorials before writing my own program and before starting threads on Elmer forums.

Yours truly

I apologize. I should have realized from their sizes that those two .tar.gz contained the case studies themselves. It also appears to me that the ElmerGUI/samples subdirectories contain several of them as well.

Great many thanks

Hello Kevinarden Sorry, I should have been more careful and entitled the request as where are the directories mentioned in the tutorial pdf ? (You are pointing me to the ElmerTutorial.pdf which I had already downloaded a week ago). I just cannot figure out which installation contains them. Thanks to...

Good afternoon This may sound like a very newbie question. However, I have no choice but to ask since I've hit-a-wall. I have just installed the nightly windows executable under the Program Files (x86) folder but I cannot find any of the directories mentioned under the ElmerTurorlal.pdf. My laptop i...

I would have saved myself the trouble of posting this question and viewers from replying if only I had read Advanced Electromagnetic Computation 2nd edition by Kalluri a day in advance since it is proven in his Appendix 16C that Neumann BCs are implicity enforced in FEM's minimizing of the functiona...

Hello again OK, first I'm going to show that for a single uniform Cartesian 2D mesh covering two dielectric regions, a very simple program can be coded (for example in C++ or Matlab). I will write the Poisson equations using FDM for the sake of argument but of course the problem could have been writ...

Hi everybody Just got acquainted with Elmer yesterday. I was wondering if the Poisson equation solver can handle the well known boundary condition epsilon1 * E1|n - epsilon2 * E2|n = sigma at an interface between two different dielectrics and with sigma being a given arbitrary surface charge distrib...
