AN ANALYSIS OF THE ERROR SOURCE IN THE WAVE PROPAGATION FORWARD NUMERICAL SIMULATION

NING Gang1,XIONG Zhang-qiang2,CHEN Chi-xun3 (1.East China Institute of Technology,Fuzhou 344000,China;2.Central South University,Changsha 410083,China;3.Hunan Province Geological Bureau of Nuclear Industry,Changsha 410011,China)  
The forward numerical simulation of the finite difference wave equation is mainly used to solve such problems as difference scheme,focal choice and boundary condition processing.The solution of these problems can play an important role in correct numerical simulation of the wave equation.Based on discussing the forward numerical simulation course of the finite difference wave equation,the authors analyzed the error source in forward simulation and the means for reducing the error.
