Elmer Discussion Forum

I am simulating electromagnetic waves through a waveguide that employs the VectorHelmHoltz solver and I am getting different results when I run it on Windows versus when its run on Linux. I have the latest version of both but these versions are different, that is the windows version is older but the...

Anyone have any ideas? I am still stuck on this problem!

Is it possible to calculate the insertion loss from the enegy functional value or some other way? This is assuming that there is energy loss within the waveguide. I am using the VectorHelmholtz module to model wave propagation in a waveguide and in the tutorial it calculated the input return loss fr...

Ok it works now! Apparently there was a previous version of Elmer installed and when calling ElmerSolver it would reference to this (old version) instead of the recent one I compiled.
Thanks for your help!

Yes, I am using the latest version from the following link: https://github.com/ElmerCSC/elmerfem

I tried compiling from source again but there still isn't a change in the energy functional values and it still says the compilation date as being in 2016!

Hi, I compiled Elmer from source on Linux with the most recent update and I am still not seeing a change! I have the following output files below, and as you can see they are identical. The first is without an imaginary part for the Magnetic Boundary load: ELMER SOLVER (v 8.2) STARTED AT: 2017/01/24...

Thanks Matthias, I'll read through the files, I've attached a case for a simplified version that essentially does the same thing incase anyone wants to try. I just gave a random non-zero value to the 'Magnetic Boundary Load im' but you can comment it out and notice that it won't make a difference to...

Thanks Anil I will try these examples.

ok thanks for responding, I guess your version had matc compiled within ElmerGrid already if you didn't receive the error.
