Pre-Analysis & Start-Up

Pre-Analysis

In the Pre-Analysis step, we'll consider how to reduce the model using periodicity. Then, we'll review the following:

• Mathematical model: (e.g.: We'll look at the governing equations + boundary conditions and the assumptions contained within the mathematical model.)
• Numerical solution procedure in ANSYS: (e.g.: We'll briefly overview the solution strategy used by ANSYS and contrast it to the hand calculation approach.)
• Hand-calculations of expected results: (e.g.:
