Efficient Finite Element Modeling Using Error Approximation Techniques

Mesh sizes of finite element models are typically based on an engineers past experience. A better method might be an automated mesh refinement based on reducing the solution error to an acceptable level. The procedure would be to analyze a rough model, determine where the maximum solution erros are occurring and refine the model in those regions. The ANSYS finite element program was used to apply this automated technique to typical structural components.
