Hola!,
Es un placer anunciar el lanzamiento y disponibilidad para descarga de NX Nastran 8.0 desde http://ftp.ugs.com/download.php, una nueva versión del solver NX Nastran de Análisis por Elementos Finitos (FEA) desarrollado por SIEMENS PLM que viene con un montón de avances importantes y corrección de errores.
La lista completa de mejoras las podréis encontrar tras la instalación del software en el fichero “NX Nastran 8.0 Release Guide“. Aquí os dejo un breve adelanto:
Dynamics …
- Residual vector options placed in the case control and more options provided.
- Reciprocal panel contributions added to give panel contributions for structural response due to an acoustic excitation.
- Modal contributions for acoustic response can be further subdivided into modal contributions by panels.
- Mode selection control (MODSEL) enabled to operate on subcase level.
- The TZERO option for transient initial conditions extended to support direct transient solution (SOL 109) and differential stiffness.

- Improved accuracy for solutions with frequency dependent element stiffness and modal damping.
Elements …

- Easier material coordinate system definitions for solid elements.
Superelements …
- External superelement geometry written to system OP2 file to support post-processing in NX.

Glue …
- Glue traction output supported.
- Improved accuracy for connected surfaces with very small separation.
- Performance improved for models with vary large number of element connection faces.
Advanced Non-Linear …

Optimization …
- Support frequency dependent properties of PBUSHT, PELAST and PDAMPT elements as design variables.
- Improve accuracy of optimization with beam section design variables.
- Update OP2 data blocks to include design cycle information.
Distributed Memory Processing (DMP) …
- Added support for frequency response optimization with SOL 200 using RDMODES solution.
- Added support for SOL 112 and restarts for SOL 111 and SOL 112 with RDMODES solution.
- RDMODES Schur complement performance improved in the partition phase.
Numerical Performance …
- Low-rank structural damping performance improved.
