I need some help regarding some kind of error message received, I had been doing the modelling regarding the heat radiation of a cell phone and wireless router to the human head/body. I am currently using the model that is already available inside the Comsol library, and whenever i change the frequency of the cell phone (PCB board) ) more than 2.3Ghz, there is a error message as shown below,
====================================================
Undefined value found.
- Detail: NaN or Inf found when solving linear system using SOR.
- Feature: Stationary Solver 1 (sol1/s1)
====================================================
Does this mean that I can't do the simulation with a higher frequency? I have search the web regarding similar problem and the solution i gotten is to change the mesh size to a finer size. But after i try it, the same error still pop out.
I really appreciate if someone can help to share their solution over here, so that others who have similar problem can learn.
Regards,
Boon Heng
