1. Analysis & Simulation MEEN 4263/64

2. Why Conduct Analyses? It’s required Will the concept work? Feasibility? Component Sizing Material Selection Optimization Failure Analyses Reverse Engineering

3. Tools for Analysis/Simulation Brain – think through the problem Calculator & paper, draw it out! Excel Matlab, MathCad CAD packages – configuration, some simulation (Solid Works with COSMOS) FEA – NEiNastran, Pro-Mechanica, COMSOL MULTIPHYSICS, simple packages from book Fluent, ProEngineer Company-specific packages

4. Analysis vs. Simulation Similar concepts, Analysis is broader & more basic. Simulation typically involves a system or complete structure, with FEA or CFD. I can simulate the vibration of a flat plate with considerable confidence that it will be correct.

5. Helpful Notes, & Potential Pitfalls When using software: Conduct a tutorial first. Conduct a simple simulation or analysis where you know the answer. Watch units, keep units, and loads/parameters consistent. Guess properties or loads if you are not sure, but document. Look for ways to verify your results, try some simple comparisons. Don’t treat software as a “Black Box”. Understand your analyses. Ask someone else to check your work. Don’t be scared to try something new or different.
