MSC Nastran 2016 is faster with new multidisciplinary analysis features. Patran 2016 improves support for nonlinear and fatigue analysis capabilities.
The software uses enhanced Automated Component Mode Synthesis (ACMS) method with Shared Memory Parallel (SMP) computing to effectively use more cores for higher user productivity. 50% parallel efficiency has been observed for 16 processors. SMP Parallelization can be used to reduce the overall wall time stiffness matrix computations and stress recovery. 75% parallel efficiency has been achieved with 4 threads with the job running 3 times faster than with one processor.
With the 3D modeling capability, users can model discrete blades and non-symmetric components of rotors and stators of rotating machinery, turbines and jet engines improving the accuracy of the rotor dynamic analyses. This type of modeling was not possible with 1D or 2.5D modeling solutions. With 3D modeling, engineers can now see what is happening locally at each blade or at the component level.
To maintain consistency with other fatigue solvers, nodal averaged stresses and strains are used for faster computation speed and a more realistic fatigue damage factors.
Skinning is implemented to create a 2D stress state on the surface of the model leading to fewer calculation points and enabling multi-axial assessments and correction on 3D solid elements.
