Design Sensitivity and Optimisation with MSC Nastran Training Course (NAS107)
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 course 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 and 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.
