It was demonstrated by the direct numerical simulation that in the case of
weakly nonlinear capillary waves one can get resonant waves interaction on the discrete
grid when resonant conditions never fulfilled exactly. The waves decay pattern was obtained. The influence of the mismatch of resonant condition was studied as well.
