Finite Element Modeling Programs for a Two Dimensional CAD Package

Eight 2-D finite element program modules are integrated into an effective analysis tool for improving the productivity in the design cycle. Three preprocessing modules can generate a finite element mesh, display the mesh, and file the finite element model into an inventory of models. Two-dimensional stress analysis, heat transfer analysis, and torsion analysis of the part can be performed. Deformed geometry and contour plots can be used to summarize the analysis results. The usefulness of this integrated approach and the cost effectiveness are illustrated by three examples.
