MSC Software is proud to announce the availability of MSC Nastran 2021.2! MSC Nastran has moved to a quarterly release cadence so customers can benefit from more frequent updates throughout the year. This is the second release of 2021 and if you missed the March release of R2021.1 please see SimCompanion for release highlights.

MSC Nastran 2021.2 Release Highlights

Some main highlights of the MSC Nastran 2021.2 include the following:

  • Nonlinear Contact:  With its smart defaults and support for geometric, contact and material nonlinearity MSC Nastran Implicit Nonlinear (SOL 400) is an ideal HPC solution for large nonlinear FEA. An example of accuracy and performance enhancements for MSC Nastran’s Contact Detection algorithm is shown in the following figure:

Improved Contact Accuracy based on Midplane for an Aircraft Panel

This release further accelerates the HPC performance of MSC Nastran Implicit Nonlinear SOL 400 with shared memory parallelism and improved PARDISO performance. For example, the results of large DOF glued contact problems like the above aircraft panel are now more accurate with a better mid-plane calculation and are more performant.

  • Vibroacoustic and Acoustic Analysis: Automotive NVH applications, such as the inclusion of noise level reduction earlier in the Automotive Design cycle, are also increasing in computational size.  MSC Nastran offers ACMS (Automated Component Mode Synthesis) to accelerate the dynamic calculation of the full body vibration with the interior trim over a wide frequency range.  This release improves the HPC scalability of ACMS and extends it into the fluid domain.  This enables Automotive OEMs to go further than ever before,  by increasing the mesh density of their acoustic cavities without impacting solution times. Further it provides powerful HPC acceleration of fully acoustic structural problems.

    Accelerate Vibroacoustic and Acoustic Analysis with ACMS support for Fluids

The most common applications for ACMS with Fluid domains are:

  • Fluid-structure interaction using Normal Modes SOL 103
  • Acoustic analysis (all-fluid domain) using Normal Modes SOL 103 or Modal Frequency Response SOL 111
  • Interior acoustics using Modal Frequency Response analysis SOL 111
  • SOL 400 perturbation analysis with fluid model from MFREQ
  • Fatigue: MSC Nastran, known for NVH and durability, is continuing to expand its offering for Fatigue life calculations.  Customers can now perform faster time domain-based Fatigue calculations  using the new hotspots, spot welds and multiple S-N curves features of the release. For example, quickly identify  hot spots susceptible to damage with Spotweld Analysis.

Fatigue Life and Damage Identification

We continue to make great strides in improvements to Nastran Embedded Fatigue (NEF) time-based fatigue analysis performance and ease of use.  In addition, users can now use the CAEFatigue GUI to import a standard Modal Transient Response (SOL 112) analysis, augment it for fatigue computation and export a run-ready bdf file.
