The original and best
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 has been developed jointly by nCode International Ltd. and MSC Software.
MSC Nastran Advantages:
Common structural analysis solutions are dedicated to one or a few analysis disciplines. To build up a comprehensive level of engineering analysis capability, multiple software solutions must be acquired, and users must be trained with each new tool. MSC Nastran features multiple analysis disciplines, enabling customers with one structural analysis solution for a wide variety of engineering problems.
MSC’s integrated solution for linear and nonlinear calculations facilitates reuse of models which saves a lot of time in pre- processing and enables us to standardize the data exchange formats for body models when collaborating with other departments or external suppliers.”
MSC Nastran is used to perform both linear and nonlinear stress analysis along with dynamic analysis for various components and sub-assemblies constituting the pump. […] Accurate predictions during these simulations is helping the C.R.I. Pumps' R&D team to reduce physical testing and product development time. The simulations are also enabling our engineers to analyze more design variants and come up with optimal designs, thus saving material cost too.”
Design optimization is a critical element in product development, but is often very iterative and requires a great deal of manual effort. MSC Nastran includes optimization algorithms that automatically seek optimal configurations in an allowed design space.
Advanced optimization processes are used on both component and system level to explore the design space in search of optimal designs. MSC.Nastran & Optimus software play herein an important role to capture the simulation process and accelerate the optimization schemes.”
Analysis models can be very large in size, requiring an extended period of time to solve. Such models can take hours or days to solve with traditional FEM applications. MSC Nastran features a number of High Performance Computing capabilities enabling engineers to solve large problems fast.
Our ability to quickly and thoroughly evaluate many design alternatives made it possible to increase the processing speed of the machine by 50% while reducing vibration levels below the previous generation of machines. [...] The first prototype provided the performance and functionality predicted by the simulation so it became the final product. The new machine was completely designed in one and a half months, faster than any similar machine.”
MSC Software provides a number of resources to support your use of MSC Nastran. Available services include:
Our MSC application engineer comes out at least once a month to see how we are doing and help us with any issues. In fact this plane would have been impossible to model without the phone support, on-site visits and consulting services provided by the MSC support team"
