Nonlinear Analysis in MSC Nastran to Reduce Design Bottlenecks

Product Marketing — Tue, 14 Jun 2016 17:00:47 +0000

Sporadic use of advanced finite element analysis (FEA) software, such as nonlinear analysis by design engineers, can result in either excessive refresher training time or a bottleneck while in the queue for an analyst. The cause is a result of different types of solvers requiring different models. Commercially available translators can help, but still require significant amounts of cleanup. However, by integrating solvers in MSC Nastran’s SOL 600, the same model in the familiar MSC Nastran format can be used for both liner and MSC Marc nonlinear analysis.

Realizing the Full Value of Aerospace Composite Design

Product Marketing — Tue, 24 Sep 2013 18:31:33 +0000

The complexity of composites vs. traditional metallic materials has forced aerospace manufacturers to complete 7-20x more tests than before across all levels of the validation pyramid. With smaller tests costing around $1k-$5K, and the larger tests costing up to $1M-$3M, a significant barrier has been presented in terms of cost and time to validate their ...
