NAS107 - Optimisation with MSC Nastran

Horizontal spacer
MSC Nastran features a comprehensive design sensitivity and optimisation capability. It is possible to design for a variety of user-defined objectives such as minimum weight or maximum frequency. This seminar covers the theoretical and practical aspects of MSC Nastran design sensitivity and optimisation: emphasis is placed on using the program to solve practical engineering problems. The capabilities of the program, including typical applications, are covered in detail. The concept of a design model is introduced. The process of optimising a structure is discussed from initial modelling to interpretation of results. Numerous example problems reinforce the material covered in the lectures.
