Descriptions for Csimsoft Trelis Pro 16.5.4 macOS

Trelis is csimsoft’s high-end commercial pre-processor for FEA and CFD, based on the time-proven CUBIT™ geometry preparation and mesh generation software from Sandia National Laboratories. For more than two decades, csimsoft and Sandia has developed CUBIT software. Now, csimsoft is Sandia’s authorized distributor for academic and commercial use.Trelis 16 raises the standard for FEA and CFD pre-processing. Companies worldwide realize how critical mesh generation is to FEA and CFD analysis. With Trelis FEA and Trelis CFD, users have specific tools for generating great meshes for either FEA or CFD solvers. Here’s why people are talking about Trelis.

Trelis raises the standard for FEA and CFD pre-processing. Companies worldwide realize how critical mesh generation is to FEA and CFD analysis. Our customers use Trelis to get high-quality meshes that give them the very best results. Here are some of the reasons why people are using Trelis for challenging simulation.

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.


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.

  • Healing
  • Tweaking Geometry
  • Removing Geometric Features
  • Automatic Geometry Cleanup
  • Regularizing Geometry
  • Finding Surface Overlap
  • Validating Geometry
  • Debugging Geometry
  • Trimming and Extending Curves
  • Stitching Sheet Bodies
  • Defeaturing Tool
  • …and many more

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.

  • Geometry Tree
  • Diagnose Geometry
  • Defeature Geometry
  • Diagnose Meshability
  • Diagnose Mesh Quality
  • ITEM
  • and more…
