NX Nastran V3 has enhanced Cquadr/Ctriar shell, a membrane element, that is easier to use and more versatile than previous versions.

The feature allows up to 64 simultaneous CPUs in a cluster versus the previous eight. Also, complex eigen solvers provides up to a 40% improvement over NX Nastran V1 for typical complex dynamics applications, such as brake-squeal analysis, and rotor dynamics. An advanced nonlinear module (Solution 601) is based on a nonlinear structural analysis solver from Adina. Postprocessing reduces the amount of results data that must be stored during the analysis eliminates additional postprocessing outside the system.
