Hey guys, I am going to simulate the frequency inference phenomenon within the brain using COMSOL. The scenario consists of implementing two pairs of electrodes on the outer surface of the skull as well as defining two different voltages with frequencies of 100 Hz and 110 Hz for the first and second electrode pairs, respectively. The brain model already exists. The problem is that we cannot create (or maybe display) the frequency interference between the two generated electric fields.
I sincerely appreciate all your help and support.

Kasra,
in case the model is all linear, you may be able to look at the two frequency components seperatly. They won't interact, only superimpose on each other.
In case of nonlinearity, you need to do a time dependent study with two explicitely time dependent signals. You will then see harmonic generation and intermodulation of the two signals.
