MSC Nastran is a multidisciplinary structural analysis application used by engineers to perform static, dynamic, and thermal analysis across the linear and nonlinear domains, complemented with automated structural optimization and award winning embedded fatigue analysis technologies, all enabled by high performance computing.
Engineers use MSC Nastran to ensure structural systems have the necessary strength, stiffness, and life to preclude failure (excess stresses, resonance, buckling, or detrimental deformations) that may compromise structural function and safety. MSC Nastran is also used to improve the economy and passenger comfort of structural designs.
Manufacturers leverage MSC Nastran’s unique multidisciplinary approach to structural analysis at various points in the product development process. MSC Nastran may be used to:
- Virtually prototype early in the design process, saving costs traditionally associated with physical prototyping.
- Remedy structural issues that may occur during a product’s service, reducing downtime and costs.
- Optimize the performance of existing designs or develop unique product differentiators, leading to industry advantages over competitors.
MSC Nastran is based on sophisticated numerical methods, the most prominent being the Finite Element Method. Nonlinear FE problems may be solved with built-in implicit numerical techniques. A number of optimization algorithms are available, including MSCADS and IPOPT. The fatigue capability in MSC Nastran uses CAEfatigue, the fastest and most robust fatigue solution on the market today.
It provides a complete solution to virtually test products, big or small, for their dynamic behavior subjected to a variety of loads, reducing product development costs, while improving safety and performance of the designs.
With highly scalable, computationally efficient algorithms for modal response and frequency response analysis, MSC Nastran is well suited to solve very large models.
It is also possible to conduct a random analysis to analyze structural response to earthquake and wind loads.
Response and shock spectra generation and analysis provide the capability to combine the modal responses to determine peak physical responses.
Additionally, transient response analysis, which is the most general method for computing forced dynamic response, enables users to compute the behaviour of a structure subjected to time varying excitations.
