Hello,

when I solution emw, it has a error :
Undefined value found.
- Detail: NaN_or_Inf_found_when_solving_linear_system_using_SOR

what's this message meaning ?
Thank you!

The first thing to do is to check the log file.

Hi Jaap,

I am simulating a nano antenna in RF module and I get this error:

Undefined value found.
- Detail: NaN_or_Inf_found_when_solving_linear_system_using_SOR

I also simulated the same model in 2D axisymmetric with the same frequency and the results were fine. Since I needed to use a different E-field as my source and the model was not symmetric anymore, I had to use 3D simulation. Moreover, I had some difficulties in meshing but I finally found a way to do the meshing without any errors. However, I only can change my mesh elements a little.

Since I used very dense meshes, do you know why I see this error? and how I can check the log file?

Thank you.
