New Trelis Features



Decomposition (Partitioning) Suggestions

The decomposition suggestions tool provides visual suggestions of ways to decompose the model into meshable volumes. Trelis checks meshability of the model and lists volumes that are meshable and those that are not. Select a volume from the "Not Meshable" list to display possible ways to cut the volume into meshable volume. Clicking the Apply button will execute the cut.

This tool is part of ITEM and is found in the Command Panels under Geometry--Webcut--Volumes--Suggestion Decomposition.

Source/Target Suggestions for Sweep Scheme

The Source/Target Suggestions tool displays suggestions for possible source and target surfaces that allows Trelis to sweep a volume. Select a volume from the list and Trelis will display source/target solutions, including their surface IDs. The Apply button will apply the sweep scheme to the volume using the selected source and target surfaces.

This tool is part of ITEM and is found in the Command Panels under Mesh--Volume--Mesh--Suggest Source/Target.

New Lite (Exodus) Meshes

Trelis has the ability to represent Exodus meshes using either a lightweight or heavy representation. Lite meshes are loaded very quickly and are easy and efficient to manipulate in the graphics window.

See "Lite Meshes" in the documentation under Mesh Generation--Mesh Import.

Improved Tetmesher

The improved tetmesher includes bug fixes and enhancements. Tetrahedral mesh scheme produces higher quality tet elements for better results.



Improved Mesh Import Dialog

The Mesh Import dialog has been streamlined and is easier to understand and use.

Users can import Mesh Geometry, Free Mesh, or Lite [Exodus] meshes. Lite Meshes are explained above.

Support for Gambit Neutral Files

Trelis now support the Gambit Neutral file format.

Import/Export Added to the Toolbar

Tool buttons to launch the Import and Export dialogs have been added to the main toolbar.


Graphics, Utilities, etc.

Enhanced Python Script Tab

Trelis is a command-driven software. At the Python level this is most apparent. The syntax for generating a command is:

cubit.cmd("enter a command string here")

Trelis 16.4 includes a new field where users can enter the "raw" command, press enter, and the Python script will be generated and sent.

This feature can be toggled on and off from the Tools--Options--Layout Options Dialog.

New Icons

Many of the icons have been refreshed, making the look of the GUI consistent and easier to understand.
