FEA Good Modeling Practices Issues and examples
FEA Good Modeling Practices Issues and examples Finite element model of a dual pinion gear. Finite Element Analysis (FEA). Good Modeling and analysis procedures FEA is a powerful analysis tool, but use it with care. Warnings ALL MODELS ARE WRONG! - SOME ARE USEFUL. An FEA program allows an engineer to make mistakes at a rapid rate of speed. (R. Miller). An error caused by misunderstanding or oversight is not correctible by mesh refinement or by use of a more powerful computer. (Cook). Finite Element Analysis (FEA). Good Modeling and analysis procedures FEA is a versatile tool, but not the best analytical tool for every problem. (Cook). An analysis is doomed to failure without sufficient consideration of all available tools to determine which is most appropriate, and sufficient pre-analysis planning to determine the required scope and level of complexity for the analysis and the required accuracy of the solution.
