This paper deals with numerical computational method on three-dimensional surface waves which are generated by a running pressure disturbance. The computational method by modified IAF scheme is investigated. The characteristics of this computational method are that the three dimensional Navier-Stokes equations are treated including viscosity terms, that the distribution of a pressure disturbance is arbitrary and that the computing efficiency is very superior compared with the ordinary MAC scheme in this problem. The validation of computational results by this scheme is investigated by comparison with results obtained by MAC scheme. The calculations of wave pattern generated by running pressure of various distributions are tried.
