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)
- 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.
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.
