摘要

This paper puts forward a node-selection method on a CAD surface model for element free method (EFM). The method first selects nodes on patch boundaries of GC~0 or GC~1 continuity, then creates geodesic lines from the selected nodes on the patch and selects other nodes on the geodesic lines via equidistant distribution. Since a geodesic line is a straight-line intrinsic with curvature on a patch, the method naturally couples the curvature distribution with the nodal distribution and produces an optimal nodal set.
