NX NASTRAN V6.1 ofrece las siguientes mejoras y novedades más importantes:
NX NASTRAN V6.1 Timeline
Dynamics ...
• Grid point force output now supported for SOL 111 and 108
• More control added to RMAXMIN and direct transient support added
• Multiple rotor speeds for rotor dynamics analyses
External Superelements ...
• Now support grid point force recovery in the system solution
• Added control of names for DMIG matrices
• Multiple rotor speeds for rotor dynamics analyses
Linear Contact ...
• Performance improved by adding options to compute optimal penalty factors
based on model characteristics. Solutions converge more quickly when optimal factors are used.
Glue ...
• New glue type option added to improve accuracy when glued surfaces are
not coincident
• Glue refinement originally supported for solid element surfaces is now
supported for shell element surfaces.
Loadings ...
• New acceleration load definitions for static loads that allow varying
acceleration loads over different parts of the model
Elements ...
• Pyramid elements are now available to transition from tetra to hex
elements
• CBUSH structural damping can now have different values for different
directions.
• Different structural damping can now be used for shell membrane, bending
and transverse shear stiffness
• Added torsional mass moment of inertia for CBAR and CROD elements
• New axi-symmetric elements added in NX Nastran 6 are now supported in SOL
200
• New nonstructural mass input cards to add mass independent of model
property cards
Numerical Performance ...
• ILP-64 (large memory) version now supported on Windows 64 platforms
• Improved performance of DMP with GDMODES
• Added multi-level implementation of DMP with RDMODES
• Performance improvements to MPYAD and SMPYAD DMAP operations
