Modular model assembly from Finite Element Models of components

Analytical engineering design is a global activity requiring efficient global distribution of analytical models of dynamic physical systems through computer networks. Finite Element Method (FEM) models are used globally to analyze the response of physical systems assembled from physical components. FEM models from different physical component suppliers often have geometrically incompatible meshes. This geometric incompatibility of mesh node placement typically requires reformulation of component models to allow those models to be assembled into a model of a system of those components. The modular model assembly introduced in this paper does not require such component model reformulation. It assembles incompatible finite element component models fast and with accuracy comparable to traditional reformulation. The proprietary geometry and material component details are not revealed during the assembly. Modular model assembly can be used to assemble distributed component models through the Internet in global engineering design. Dynamic examples are provided.;A paper discussing this work written by Zhen Ren and Clark Radcliffe has been submitted to 2008 Dynamic Systems and Control Conference of ASME.
