• Multi-Stage Simulations: Ablation

  • Support of ATAS (Advanced Thermal Analysis Software) analysis with Model

  • Sections has been extended to support the Streamline Pyrolysis Model

  • Stretch and the Multi-Zone remeshers are now supported in Model Sections

• Multi-Stage Simulations:Performance

Model section files can be compressed to significantly reduce file size and overall simulation time

• Contact Modeling Performance

  • Faster performance of contact for exact CAD geometry (3D NURBS based geometric bodies with many trimming curves)

  • Faster performance in 2D contact simulations using the segment-to-segment method.

• MUMPS Solver Performance

  • ​General speed-up in many simulations when using the MUMPS solver due to a more efficient implementation

  • Reduced memory consumption on the parent domain with the default pre-conditioner when using DDM.

• Mentat Performance and Other Improvements

  • Faster performance of Mentat via more efficient redraws, most noticeable with larger models

  • Improved speed of execution for procedure files

  • Mentat now allows the creation of images of arbitrary size from the current graphics window

• Reinforcement Enhancements (Tire Modeling)

  • ​Cylindrical expansion feature for rebar elements has been updated to include Pre-Strain

  • Improved checks are made for the physical validity of the post-expansion orientation angle

  • Consistent rebar properties are established in 3D structures even when a coarse mesh is used in the circumferential direction to accelerate convergence

• MARC Verification Guide

The Marc Verification Guide has been updated with 52 sample NAFEMS benchmark problems.

The examples are organized according to specific areas: Linear Elastic, Heat Transfer, Free Vibration, Forced Vibration, and Nonlinear Benchmark problems.
