- ITEM Wizard
- Immersive Topology Environment for Meshing (ITEM) is a wizard-like tool that walks users through the meshing process. It uses Trelis's power tools for easy geometry cleanup and for generating the best possible mesh. The ITEM process includes:
- Import/Create Geometry
- Setup Mesh Parameters
- Prepare Geometry
- Mesh the Model
- Validate Mesh Quality
- Define Boundary Conditions
- Export the Mesh
- ITEM Watch the video on how to use ITEM
- Geometry Creation
- Engineers spend up to 65% or more of their time preparing geometry for meshing. Trelis has powerful tools for easier clean up and defeaturing so that you can spend more time with the results.
- There are three primary ways of creating geometry for meshing in Trelis.
- Geometry primitives for building models
- "Bottom up" geometry from vertex, curves, and surfaces
- CAD files imported from another application
- Trelis supports many common CAD formats. See Trelis Data Translators for more information about supported file formats.
- Geometry Transforms
- Geometric entities can be modified in Trelis using transform operations, which include align, copy, move, reflect, restore, rotate, and scale.
- Boolean Operations
- Trelis supports powerful boolean operations to intersect, subtract, and unite geometric entities.
- Decomposition
- Geometry decomposition is often required to generate an all-hexahedral mesh for three-dimensional solids. "Web cutting" is cutting an existing body into two or more pieces through the use of a cutting tool. Trelis has several methods for making web cuts.
- ITEM Watch our tutorials and vidoes on using Trelis's tool to decompose models for meshing.
- Cleanup and Defeaturing
- Sometimes models imported from a CAD program will either provide too much detail for mesh generation or the geometry is deficient. This can be corrected by making changes to the model. Trelis has excellent tools for cleanup and defeaturing including.

- Power Tools
- Trelis's Power Tools help users to identify problems with geometry before meshing and recommend solutions for getting it ready for meshing. After a mesh is generated, additional Power Tools check the mesh quality based on various metrics and values the user specifies.
