Issue with multiply frequencies on a dipole antenna.

So, I'm using the standard simulation of a dipole antenna(link below) and every thing worked fine, but when I try to use the range when on the Study 1>Study Setting>Frequencies the program try to simulate and after almost a day will give me an error message saying that the "Comsol failed to find a solution for the iticial parameter matrix has zero on diagonal".

I'm trying to make a simulation to observe the behavior of the impedance when I vary the frequencies.
