45 - Interpolation and Shape Function

Abstract

This screen demo introduces an educational function of VisualFEA, related to intra-element interpolation of nodal values using shape functions. This feature of the program is intended to help understand the nature of the shape functions and computational aspects of interpolation. The characteristics of element modeling can be examined through the graphical representation. They include the inter - element continuity related to compatibility of the shape functions between adjacent elements.
