Hello!,
A new NX Nastran release V9.0 containing many enhancements and corrections is available since last October 3, 2013 for platformrs Linux (64-bit) and Windows (64-bit Intel). This is the same NX Nastran release that will be integrated with the new version of FEMAP V11.1, available in the worldwide market next month of November, 2013.
A complete list of enhancements and corrections can be found in the NX Nastran V9.0 Release Guide (to learn more you can visit also my blog at A quick review of enhancements includes:
Dynamics ...
• New AF (Amplitude-Frequency) eigenvector normalization method.
• Laminate ply results recovery for shell elements in transient solutions.
• RMS von Mises stress now computed for random analysis.
• Residual vector defaults changed to make usage easier.
• Rotor dynamic forces now computed in SOL 101 to allow maneuver load simulation.
• Rotor dynamic bearing element extended to support stiffness and damping as a function of displacement. Currently limited to use in SOL101.
Elements ...
• Improved stress recovery for tetrahedron elements used in SOL 106 or SOL129.
Multi-step Nonlinear ...
• A new NX Nastran solution sequence, SOL 401 - NLSTEP, has been created. It is a multistep, structural solution which supports a combination of static (linear or nonlinear) subcases and modal (real eigenvalue) subcases.
Glue Connections ...
• Option to output glue stiffness matrix in DMIG format.
Advanced Non-Linear ...
• New MATPLCY material model is available for solutions 601 and 701 to define plastic-cyclic materials.
• Bolt preloads on 3D element bolt representations.
• Edge-Edge glue connection support for 2D solid elements.
• Support rotational loads applied to a subset of the model.
Optimization ...
• Equivalent Radiated Power (ERP) added as a DRESP response quantity
Process Improvements ...
• A new system cell to optionally turn off the line numbers in the PUNCH file
• Multiple ACCEL1 entries with the same SID are now permitted
• Option to suppress DMAP compiler warning messages that arise because of undefined input or output to DMAP commands.
• Option to control the numerical precision of matrix data that NX Nastran writes to OP4 files for EXTSEOUT and MBDEXPORT.
Parallel Processing (DMP and SMP) Solutions …
• Improved algorithmic performance for RDMODES. In one test case of a car body model that contains 384,000 elements, 391,000 grids, and 2,300,000 DOF, the elapsed time is reduced by 50%.
Numerical Performance ...
• Option for frequency response solution to be performed with in-core memory. In many large models, this provides significant back-end solution performance.
Best regards,
Blas.
