Hi, experts!
I am novice and want to ask: Is it possible to calculate overall conductivity of the composite containing high conductive nanoparticles in almost non-conductive media?
If yes, which modules and functions should I use? Probably there are some nearest examples.
Thanks in advance, I will be grateful for any advice and help

Hi
I am not sure if this is a Comsol problem at all. A situation like yours is usually analyzed with the percolation theory. The conductivity is zero before the nanoparticles create a continuous path across the sample. There are Matlab codes available in the web that calculate this.

You may set a potential difference across the sample and integrate current in either ends. Then Ohm's law. You may also scan the potential difference with parametric sweep.
