Numerical simulation is a method that uses computers to solve engineering,physical,and even natural problems by numerical calculation and graphical display.With the development of highperformance computing,numerical simulation has been widely used in structural deformation research of sedimentary basins and has achieved fruitful results.Based on a review of previous studies,four main numerical simulation methods are introduced:finite element method,finite difference method,boundary element method,and discrete element method.Then,the results of previous studies have been summarized to conclude the effects of several first-order parameters on the geometry and evolution of foldand-thrust belts in basin deformation.This paper aims to provide a comprehensive understanding of numerical simulation and to guide future researchers to apply this method in basin deformation.Finally,the limitations and future perspectives have been discussed.
