Elastic Modeling Based on Advection Equations

P264 Elastic modeling based on advection equations Introduction 1 In elastic wave propagation modeling the FDM (Finite Difference Method) has been widely adopted because of its simple implementation. However the numerical dispersion and computational stability are required to be considered carefully. There are some known methods to reduce numerical dispersion for example; FDM with staggered grids (Vireux 1986) the high order differential operator (Levander 1988) and FCT method (Fei and Larner 1995). In this paper the CIP (Cubic Interpolated Profile) method is proposed as a highly accurate and stable algorithm to solve advection equations. The basic computation schema was developed
