LMS Virtual.Lab Component Strength and Fatigue for NASTRAN provides an integrated solution for component-based strength and fatigue simulation. Its tools include static strength analysis based on static load cases, dynamic strength analysis based on dynamic load cases and numerical fatigue life prediction methods.
Durability teams can prepare, automatically drive, and post-process MSC.NASTRAN based static stress analysis cases, all within the same LMS Virtual.Lab user interface. Users import a MSC.NASTRAN mesh or start from a CATIA/CAE mesh automatically generated from a CAD model. From the template-based interface, they can check the quality of the mesh, complement and modify the mesh, apply constraint definitions and loads inputs, define the analysis case and launch the MSC.NASTRAN solver. This integrated approach eliminates time-consuming data handling and file transfers, and makes the setup of a strength analysis very straightforward. Dedicated post-processing utilities allow to quicky zoom in on the stress hotspots. In parallel the influence of the dynamic loading conditions on the fatigue performance can be evaluated using dynamic stress animation. Also included are LMS Virtual.Lab Component Fatigue based numerical fatigue life prediction methods for detailed analysis. Design modifications are supported through the Virtual.Lab embedded mesh modification utilities.
Through the CAA V5 based associativity concept, users can automatically execute consecutive simulation runs, during which different design options and/or load cases seamlessly run through the complete analysis process. Evaluating a new design only requires plugging in the modified mesh and the analysis is automatically restarted – no need to redefine load input points, constraints, etc. This supports durability teams in experimenting with multiple design options and identifying the best solutions before starting physical prototyping.
