New Trelis Features

Meshing.


Improved Paving (quadrilateral meshing)

The paving algorithm that has become a standard worldwide for quadrilateral mesh generation is now even more robust in its ability to mesh complex surfaces.


Improved Tetmesher

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

Geometry.


Improvements to geometry creation using lofting

Improvements have been made to the create lofted volume command so that the volume creation better lofts complex entities. See Trelis Help for more information about the create lofted volume command.

Import/Export.


Improved Abaqus and Patran Exports

The Abaqus and Patran exporters have been improved to better import and export mesh and boundary conditions in Abaqus .inp and Patran .neu fomats.

Graphics, Utilities, etc.


New Custom Toolbars

The Custom Toolbar architecture has been completely redone. Users can create custom tools as in previous versions of Trelis, but the toolbars can now be used as workflow managers. Toolbars may include standard buttons, journal files, Python scripts, and command panels. Toolbars and workflows may be exported and imported.


Command Panel Button Hierarchy Change

The button hierarchy for the Geometry command panels is now action based rather than entity based. Other button hierarchies have been modified with a focus on ease of use.


New Icons

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


New Context Menus for Boundary Conditions

Context menus for list, draw, and draw add have been added to boundary condition objects in the model tree.


New APREPRO Functions

Three new functions have been added to the APREPRO editor. They are NumBlocks, NumSidesets, and NumNodes. Please see documentation for information on using these functions.
