The growing competition to compress Development Time of an Electromechanical Product mainly in Automotive Industry has resulted into more focus on pre-validation of Product Design which is also called Design Verification. It involves mainly verifying the Product with end customer boundary conditions into Simulation Tool and predict the behaviour after application of defined load cases without building and testing on actual physical samples. Simply called Computer Aided Engineering (CAE) this not only gives confidence to the Product Designer but also saves lot of time and cost involved in the iterative physical testing. Now as this verification is crucial, so it is also important to understand if results are reliable enough to implement the findings into our Product Design. This paper focus mainly on quality of Simulation Results in CATIA V5 by characterization of Global Error Rate and it’s impact on different simulation set-up and parameters.
