MSC Nastran Update Provides Faster Performance for Large Models

MSC Software announced the new release of MSC Nastran 2013.1. According to the company, new capabilities in this version provide engineers with faster performance for large models, ease of use, and nonlinear analysis improvements.

Automated Component Mode Synthesis (ACMS) delivers further speed enhancements with 10 percent to 30 percent time reductions in the ACMS portion of large scale simulations, reducing the time and cost of modal and automotive NVH simulations, the company says.

Gas turbine and aircraft engine manufacturers can achieve more accurate prediction of the rotordynamic performance of structures with rotating components using the new axisymmetric harmonic elements. Users can model geometrically axisymmetric structures subjected to general non-axisymmetric loading represented by harmonics, allowing engineers to capture the effects of the complex geometry of the rotors.

The new release also features improved integration between Nastran 2013 and SimXpert 2013, so very large models can be visualized. Micromechanical composite material models are now achievable utilizing the e-Xstream Digimat technology within SOL 400 and SOL 700.

Temperature mapping of multi-degrees of freedom heat transfer shell elements has been enhanced, providing more accurate temperature distribution, resulting in higher fidelity stress results in sequential thermal-mechanical analysis, the company says.
