It's the energy that is minimized, not the forces. Anyway, the forces are
very large, but even zero forces do not guarantee to be at the minimum.

 I don't understand   what does the stars mean  (pressure)

the stars mean that your pressure is so large that it exceeds the format.
This is a clear indication that there is something very wrong in your
calculation

and what i have to do to obtain a pression of zero
