The CompSim-Geometry and Meshing Team is pleased to announce Version 16.08 of the CUBIT™ Geometry and Mesh Generation Toolkit. The following is a sampling of new capabilities and improvements introduced in CUBIT™ 16.08. See the CUBIT™ 16.08 Release Notes for a complete list, which includes many resolved user tickets and new capabilities developed in support of the Next Generation Simulation (NGS) initiative.

What’s New…

Automatic Reduction of Thin Volumes

With the new thin volume automatic reduction functionality, 3D volumes can be automatically reduced for shell modeling while maintaining a contiguous 2D connected set of sheet bodies. Blocks are automatically created and attributed with a computed thickness and loft factor. Additional commands allow for visual inspection of the reduction and exporting a csv file containing reduction details for input deck creation.

New support for SGM with geometry classification

When importing a model into Scalable Geometric Modeler (SGM), machine learning based classification is now available. Both identification of categories and training of categories is available. For example, if a model containing bolts is loaded into SGM, one can use the following command syntax to identify bolts:

classify volume x
list volume with category "bolt" ids

Usability Enhancements

The color specification in CUBIT has been enhanced to allow for RGB and RGBA color specification in any command. This is an addition to being able to use color names and ids. The color choosing dialog in the graphical user interface has been enhanced to support choosing any RGB color. Using the RGBA specification can be useful when making individual surfaces transparent. The alpha value can range between 0.0 and 1.0 where 1.0 is opaque and 0.0 is transparent/invisible. To make a surface transparent, issue the command:

color surface 1 rgba 0.5 0.3 0.9 0.3
