NAS120 - Linear Static Analysis using MSC Nastran and Patran

Horizontal spacer
This seminar introduces basic finite element analysis techniques for linear static, normal modes, and buckling analysis of structures using MSC Nastran and Patran. MSC Nastran data structure, the element library, modeling practices, model validation, and guidelines for efficient solutions are discussed and illustrated with examples and workshops. Patran will be an integral part of the examples and workshops and will be used to generate and verify illustrative MSC Nastran models, manage analysis submission requests, and visualize results. This seminar provides the foundation required for intermediate and advanced MSC Nastran applications.
Length: 
5 Days
Pre-requisites : 
No previous finite element analysis or computer-based modeling experience is required. A basic knowledge of statics and strength of materials is highly recommended
