Abstract

On the research of 3-Dimension Numeric Manifold Method (3DNMM), we discuss the characteristics of simplex integration algorithm and analyze the accurate character of 3DNMM results. Firstly, we analyze the accuracy of the simplex integration through comparing the theoretical results with calculated results, which parameters include the volume and center of gravity. The results show that the relative error between calculated results and theoretical results is about 10 -15-10 -14, and the graphics conditions have minimal impact on integral results. Then, we compare the calculation results from 3DNMM with theoretical results, which include motion of a free falling body, deformation of the cantilever beam and slipping on the tilt surface. These comparison analysis shows that 3DNMM has the characteristics of high precision and can reach good simulated effect in limited elements.
