NAS122 - Basic Dynamic Analysis using MSC Nastran and Patran

Horizontal spacer
The course covers a wide range of dynamic analysis topics from basic to advanced using an integrated approach. Patran is used for data set up and post-processing and MSC Nastran is used for the solver. Many unique practical hints and tips are given which do not exist in other material. Case studies are used in each topic to help understand the physics and engineering behind the techniques in a practical way. A comprehensive set of over 20 fully detailed student workshops is used to obtain real "hands on" experience. A strong emphasis is placed on engineering process so that the student can rapidly relate the course to his or her project needs.
