7 Discussion Why Develop Structural Analysis Simulation Tools? Cost Savings Significant Time Savings through automated analysis. Libraries of Material Properties reduce Fat Finger errors & minimize rework. Role Of Analysis and Simulation in Design Process is Growing Old Ratio: 6 Design /1 Stress; New Ratio: 1 Design/1.2 Stress Accurate and Repeatable Solutions Reduce Rework, Increase Accuracy Modernize Existing Legacy Tools Engineers are used to GUI based applications Make Tried and True methods and codes easier to use Automate Documentation Analysis artifacts should be automatically retrieved and stored. Electronic Data Storage 7 Develop Tools to Reduce Costs!
