%X The iterative simulation equation set of high accuracy surface modeling,HASM3,is upgraded into HASM4 on the basis of numerical tests repeatedly in order to give a solution to the computing time problem of HASM3.The experimental results show that HASM4 has greatly shortened the computing time comparing with HASM3.With increase of total number of grid-cells in the computational domain,the computing time of HASM4 becomes shorter and shorter,which can be formulated by a function of negative power exponent.In the meanwhile,iteration times of HASM4 for reaching its convergence rectilinearly decrease with increase of total number of grid-cells in the computational domain,comparing with the ones of HASM3.HASM4 has not only shortened computing time,but also enhanced simulation accuracy,comparing with HASM3.
