Csimsoft Trelis Pro 16.5.4 Overview

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. You can also download ZBrush 2019.

Some companies need the tools to generate meshes for both FEA and CFD analysis. Trelis Pro contains all the features of Trelis FEA™ and Trelis CFD™ in one package.

Features of Csimsoft Trelis Pro 16.5.4

Below are some amazing features you can experience after installation of Csimsoft Trelis Pro 16.5.4 Free Download please keep in mind features may vary and totally depends if your system support them.

High-end Hexahedral, Tetrahedral, and Hybrid Meshing

  • For more than two decades, we’ve been developing the core meshing algorithms that make Trelis such a powerful mesh generation tool for CFD and FEA. We love hearing from users that they can mesh models that other leading tools can’t mesh.

Powerful Geometry Creation and Cleanup Tools

  • Trelis allows users to import geometry from many popular CAD programs or to create models using primitives or from the bottom up. We estimate that engineers spend up to 65% of their time preparing geometry for meshing. We developed a significant amount of the Trelis development creating powerful tools for clean up and defeaturing.

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.

ITEM Wizard

  • Immersive Topology Environment for Meshing (ITEM) is a wizard-like tool for geometry cleanup and mesh generation. The ITEM Wizard uses the power tools to guide users through the meshing process. The ITEM steps are:
  • Import/Create Geometry
  • Setup Model
  • Prepare Geometry
  • Mesh the Model
  • Validate Mesh
  • Define Boundary Conditions
  • Export the Mesh

Scripting, Journal Files, and Parameterization

  • Trelis utilizes a rich command language that can be stored as a journal file. These scripts can be used to parameterize the construction of models to determine design sensitivity and to capture repetitive meshing processes.

Boundary Conditions

  • Trelis support the application of boundary conditions to sidesets, nodesets, element blocks, and to geometric entities. Trelis FEA and Trelis CFD support a variety of FEA and CFD boundary conditions, respectively. Trelis Pro supports both FEA and CFD boundary conditions.

Solver Format Support

  • Meshes generated with Trelis are exported with specified boundary conditions to many standard FEA and CFD formats. If Trelis doesn’t support a particular file format, Trelis’s public mesh export API allows users to write their own exporter for any file format.

Customizable Components

  • Trelis users use the CubitInterface API (C++ and Python) to extend Trelis by building custom components that are focused on solving a specific problem or type of problem. Trelis’s GUI components are extensible and modifiable so users can customize the interface to suite their needs.

Intuitive Environment

  • Trelis includes both a convenient command line interface with an extensive command language as well as a polished graphical user interface environment.
  • New features were added to make geometry preparation easier and to offer support for importing and exporting more file formats. Core meshing and sizing algorithms have been improved to give better mesh quality. Significant improvements to the GUI makes Trelis even easier to use.
