Introduction to TrueGrid

About TrueGrid®

TrueGrid® software is advanced meshing technology for FEA and CFD simulation codes. TrueGrid®’s unique approach to mesh generation saves time and produces quality, near orthogonal elements. Even complex models are meshed to superior quality.

• The Projection Method
  TrueGrid® meshes are formed more quickly and easily using the projection method. The projection method takes the menial tasks out of capturing geometric features in the mesh.

  

• Multi-Block Structures
  TrueGrid® uses a multi-block approach to mesh generation. Block structured hex meshes produce the highest quality meshes, ensuring accurate results. Multi-block structures minimize the effort of constructing complex models.

  

• No Geometry Clean-Up
  TrueGrid® faithfully imports CAD/CAM and solids model surfaces and there is no need for geometry clean-up.
  You can import your CAD/CAM or Solids Model in the standard IGES format and save time and frustration because your IGES surfaces will be flawless.

  

• Parametric and Scripting Capabilities
  TrueGrid® is both an interactive and batch mesh generator. In batch mode you can edit the scripting file to produce a parametric mesh. Save time by creating one quality parametric model to produce many variations.

  

• Pre-Processing
  TrueGrid® is a complete preprocessor
  

  for the simulation codes that it supports.
  TrueGrid® will write the entire input deck for a simulation code. The pre-processing tool in TrueGrid® makes it possible to take advantage of the advanced features available in the simulation code.

• Geometry Library
  TrueGrid® has a built in geometry library so users can create their own geometry or add surfaces to geometry already imported from other files.
  • Planes, spheres, cylinders, ellipsoids, cones, and tori
  • 2D and 3D lines, polygonal curves, and arcs
  • 2D and 3D cubic spline and NURBS curves
  • 2D and 3D curves by algebraic functions
  • 3D curves composed of edges of surfaces
  • 3D curves from the intersection of surfaces
  • Curves projected onto surfaces
  • Concatenation of any set of 3D curves
  • Curves of interpolation
  • Lofted curves
  • Surface edges and contours
  • Surfaces of revolution
  • Ruled, swept, and pipe surfaces
  • Surfaces blended from 3 or 4 curves
  • Cubic spline and NURBS surfaces
  • Mesh and polygon surfaces including STL
  • Combination of surfaces to form composites
  • Surfaces by algebraic functions
  • General transformations and normal offsets can be applied to the geometry

Licensing

• Annual Licenses
  An Annual License is a lease of the TrueGrid® software for one year. The user has access to upgrades and technical support for the duration of the year.
• Perpetual Licenses
  A Perpetual License gives the right to use TrueGrid® software forever. The user has the option to pay annual maintenance which gives access to upgrades and technical support for one year. This can be renewed every year.
• Network Licenses
  TrueGrid® can be run on any supported computer on your network. For each license purchased, one instance of TrueGrid® can be run on the network. When multiple licenses of TrueGrid® are purchased for a network, then that number of instances can be run simultaneously. Additional requests to run TrueGrid® will be placed into a queue, and TrueGrid® will run according to those requests as soon as an instance becomes available.

Trial Licenses

• A fully functional, free Trial License of TrueGrid® is available. The Trial License is valid for 60 days and comes with complete documentation and full technical support. Contact ACT to find out how to receive a Trial License.

Upgrades and Maintenance

• Maintenance is sold on an annual basis for a Perpetual License in order to receive upgrades and technical support.
