In this paper, the truncation error of discrete similarity method is analyzed and studied. The calculation methods and formulas of truncation error and error bound are obtained. The variation rules of accuracy of truncation are demonstrated and the divergence problem of error tolerance bound is solved. Simulations can be given both simulation results and error estimates, improve the trust of the simulation results, improved simulation of discrete similarity method.
