Abstract

This paper describes a local interpolation method and proposes its use for the generation of three dimensional surface meshes. Large displacements from non-linear finite element analysis may be represented realistically by mapping a two dimensional adaptive un-structured mesh onto the displaced geometry of the initial coarse finite element mesh. Hence an interpolated three dimensional surface may be generated having first order derivative continuity from a relatively coarser initial mesh. Through the use of adaptive meshes greater resolution is readily achieved in the areas of the surface where it is most needed i.e. the regions of high displacement variations.
