The new features of MSC Software Corp.’s MSC Nastran 2013 deliver customization and broader solution capabilities that generate time savings in automotive and aerospace simulation workflows. The new release integrates fatigue analysis capabilities within MSC Nastran. Engineers can now calculate fatigue damage and life using the MSC Nastran solver without the need to export results to a separate fatigue solution with Embedded Fatigue Analysis. Through Poroelastic Material Modeling, the new version supports the poroelastic behavior of trim components (used extensively in automobiles and aircraft to dampen the vibrations and improve the cabin comfort for the occupants) to analyze the vibroacoustic performance of the vehicle by modeling the complex multiphysics of the fluid-solid interaction. According to MSC, this results in improved simulation accuracy. The new release also provides advanced nonlinear, explicit nonlinear, and high-performance computing features.
