12.- Nueva versión de NX NASTRAN V8.0

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.
  • Flex body export (MBDEXPORT) for the state-space format extended to give    acceleration response variables in addition to the existing displacement and velocity response variables.
  • Improved accuracy for solutions with frequency dependent element stiffness     and modal damping.

   Elements …

  • Support linear and parabolic plane stress (CPLSTSx) and plane strain elements (CPLSTNx) in more solutions.
  • New 2D edge load support.
  • Non-linear materials support for solid parabolic elements in SOL 106 and 129.
  • Pyramid elements (CPYRAM) can be used with hyperelastic materials in SOL 106 and 129.
  • Support composite material definitions for solid Hex and Penta elements.
  • Easier material coordinate system definitions for solid elements.

   Superelements …

  • External superelement geometry written to system OP2 file to support  post-processing in NX.
  • Control of loads on external superelements improved for the system analysis.
  • DOF definition for external superelements in SOL101 made consistent with SOL 103.

   Linear Contact …

  • Support contact for inertia relief solutions.
  • Improved accuracy for contact pressure output.

   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 …

  • Support variable thickness for plane stress elements.
  • Support edge load for plane stress/strain elements.
  • Added visco-elastic properties for both hyperelastic and non-hyperelastic materials.
  • Support Mullins effect with hyperelastic material.
  • Support combined creep with elastic/plastic strain.
  • Support new material orientation input for orthotropic materials.
  • Support CBUSH element.
  • Support direct input of stiffness and mass matrices with DMIG input.

   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.
  • Factor caching enhanced for improved modal solution performance.
  • Improved timing constants for SMP solutions.
