This core package is a complete NASTRAN solution for static stress with linear material models, natural frequency (modal), critical buckling load and steady-state heat transfer analyses.

This core package includes the capability to import FEA models that are stored in a NASTRAN (.bdf, .dat, .nas) file and complete data exchange with third-party software, such as acoustics and fatigue applications, through industry-standard NASTRAN files (.bdf, .dat, .nas, .op2) by writing input deck data and binary output files that are NASTRAN compatible.

Static stress analysis capabilities include the use of linear material models, weight, center of gravity and mass moment of inertia analysis and linear contact. Natural frequency (modal) analysis determines a part's natural frequencies and a
