SIMBAT User's Manual

Abstract : This manual describes the operation and instructions for execution of the Conditional Ocean Wave Simulation Model (SIMBAT). SIMBAT is a high performance FORTRAN F77 based computer model that uses the Fast Fourier Transform (FFT) to produce ocean wave properties for ocean engineering applications. The model assumes the wave properties form a gaussian stochastic process. SIMBAT may be used to perform a conditional or unconditional simulation. A conditional simulation uses a measured or existing input time series and forces the simulated wave properties to adhere to the input time series but also follows the laws of multivariate normal probability. An unconditional simulation uses a measured or created ocean wave spectra to randomly simulate the ocean wave properties. Program features include: creation of directional ocean wave spectra; water particle kinematic stretching; conditioning time series using an input time series less than or equal to the simulation length; use of Legendre orthogonal polynomials for post creation of wave properties by program CKPOLY; and error checking. Examples problems are included.
