CUBIT™ 15.7 Released October 20, 2020

The CompSim-Geometry and Meshing Team is pleased to announce Version 15.7 of the CUBIT™ Geometry and Mesh Generation Toolkit. The following is a sampling of new capabilities and improvements introduced in CUBIT™ 15.7. See the CUBIT™ 15.7 Release Notes for a complete list, which includes capabilities developed in support of Next Generation Simulation (NGS)

What’s New…

  • Composite Tet10 Meshing enhancements include new normalized inradius metric, commands for collapsing poor quality tri/tet elements, options to name mesh intersection group, and new criteria for node projection.
  • Sculpt has been enhanced to better fit the overlay grid to the input STL geometry by associating grid edges to STL curves. Also, improved color smoothing , a new option to automatically insert void material , and a new option to select the htet method for splitting hexes in to tets has been implemented.
  • New machine learning research capabilities such as classifying common mechanisms parts, simplifying these parts, and suggesting defeaturing tools to improve meshing outcome have been made production ready. New assembly diagnostics , visualization, and resolution for gaps, overlaps, misalignments, contacts and mergeable entities have been implemented.
  • Uniform Mesh Refinement (UMR) tool now uses an efficient streaming pipeline with low memory requirements. On recent CPUs with an SSD (solid state drive), UMR can write a refined mesh up to 4 billion elements in only a few minutes and millions of elements in seconds.
  • New Gitlab repository has been created to manage user-developed Python scripts. These scripts are tested nightly against multiple versions of CUBIT™ on all three platforms. New CubitInterface functions have been implemented to support Python scripting.
  • New GUI improvements include enhancements to tetmesh and trimesh command panels , custom options for reduce command, and context menus for “Draw Volume Overlap”, “Draw With Nearby”, and “Draw with Neighbors”.
  • When naming entities in CUBIT™, names are now case insensitive. If a model contains volumes with same name, the volume names will be automatically modified during import. Please refer to the user manual if you want the old behavior.

Limitations in CUBIT™ 15.7

How to Get it…

CUBIT™ is available to anyone on the Sandia LANs. CUBIT™ 15.7 will now run automatically from the Linux command prompt, replacing CUBIT™ 15.6. It is also licensed free of charge for government use outside of Sandia. If you are a current CUBIT™ licensed user, you may download CUBIT™ 15.7 from the CUBIT™ Download Webpage. See CUBIT™ Licensing for information on obtaining a license.
