Re: Simulation of the electric field generated by 4 electrodes
Hi, doing the simulations I'm seeing a strange value of the electric field. I've attached the screenshot of the mesh, the potential and the electric field calculated with this sif file: Header CHECK KEYWORDS Warn Mesh DB "." "." Include Path "" Results Directory "&...

Re: Simulation of the electric field generated by 4 electrodes
Hi Peter, I solved the issue using the step check tool in Netgen. It creates the required connections obtaining a single body with all the objects integrated. The last think I was not able to reproduce is the graph. It seems you have taken a section of the sphere volume looking it from the top. So, ...

Re: Simulation of the electric field generated by 4 electrodes
Hi, I did it, but with no results. I tried to understand why I have this result and I think that the problem could be due to the mesh. It seems that the mesh of the outer material and the mesh of the electrodes are not connected. I have created 3D volumes for each object and I have placed them in th...

Re: Simulation of the electric field generated by 4 electrodes
Hi Peter, I checked again with more detail the tutorial you suggested me. Now I found the way to have the solver working: I have to eliminate the body definition of the electrodes leaving only one body, as explained in the tutorial. The sif file is now: Header CHECK KEYWORDS Warn Mesh DB ".&quo...

Re: Simulation of the electric field generated by 4 electrodes
Hi Peter,
the solver doesn't accept an empty or zero value for the equation.
So how can I say it to solve only the external material?
Thanks
Claudio

Re: Simulation of the electric field generated by 4 electrodes
Hi, thanks for the suggestions. Just one question. Since all the materials are conductors (stainless steel and human tissue simulated with water having a specific conductivity), and the relative permitttivty of the stainless steel is not foreseen in the material library, what value do you suggest to...

Simulation of the electric field generated by 4 electrodes
Hello, I'm trying to simulate the electric field genrated by 4 electrodes into a material. The electrodes are activated as couple and not all at the same time. I'm using the "Static Current Solver" to calculate the potential and the "Flux and Gradient Solver" to calculate the gra...

Re: Installation on ubuntu 16.04 LTS
Hello, after the evaluation of several forums, I think I solved my problem in an acceptable way. The solution, in my case, has been the following: 1) create and add into the .bashrc file the variables : ELMERGUI_HOME=/usr/share/ElmerGUI ELMERSOLVER_HOME=/usr/share/elmersolver ELMERLIB=/usr/lib/elmer...

Re: Installation on ubuntu 16.04 LTS
Hello, I'm writing in this post because I'm still having the same problem: Elmer was working perfectly on ubuntu 14.04 but after the upgrade to 16.04 I had to reinstall it. I have reinstalled elmer 8.2 from the PPA and now I'm seeing the message shown in the first post. I've tried to export the vari...
