Re: problems with electro-thermal simulation

Hummm... I'm starting to convince myself that theres nothing wrong with the simulation. In fact, I'm not accounting for any sort convection, heat conductivity of air (0.025) is miserable and if you start to increase it up to that of copper you will see that copper trace temperature (when heat conduc...

problems with electro-thermal simulation

Hi all, I'm trying to setup a steady state simulation to understand the raise in temperature of a trace on a pcb. The starting model is very simple, just a small PCB with a straight trace (20mm long). All is immersed in air. Dimensions are ok, I've checked this by comparing the analytical solution o...

Re: Can't open module file ‘zoltan.mod

Hi Peter, I understand, in any case I managed to find the problem. The directory that needs to be removed before launching elmer_install.sh had its name changed from "builddir" to "builddir_devel" Can you please update the "Rreadme1st.tx" file in the virtual machine download directory to address the...

Re: Can't open module file ‘zoltan.mod

HI all, just an update, I've tried the commands "git submodule sync" and "git submodule update --init" in the Source directory and they worked (I could see the directory Zoltan_v3.83 in contrib) however after saying "./elmer_install.sh" I've got the same compelling error as before /home/elmeruser/So...

Re: Can't open module file ‘zoltan.mod

Hi all, I'm having a similar problem (can't open module file 'zoltan.mod') while trying to update Elmerfem in the virtual machine (I've downloaded the most recent version of VA). Assuming the problem is the same. In what directory do I need to run the commands below? git submodule sync git submodule...

Re: Application fields of Elmer

Hi Peter,

that is very interesting, I'll have a go and see how it works.

I assume that the Conforming BC examples can be found in the test cases directory. Please let me know if there are any other sources.

Thanks,

Marco

Re: Application fields of Elmer

Hi all, I'm using Elmer mainly for electromagnetics. Sometimes I do mechanics and acoustics. I have't been active in the last year but before that I have seen big improvements in electromagnetics. The part where I would like to see more developed is mortar periodic BC and associated solver convergen...
