XYZ Scientific Applications Inc.

XYZ has been developing the world's most sophisticated 3D hexahedral meshing system since 1991. TrueGrid is a premier preprocessor for hexahedral and quadrilateral grid and mesh generation. TrueGrid's unique projection method enables the user to import CAD geometry and interactively generate high quality, structured, multiple block meshes in a fraction of the time taken with other mesh generators. Surfaces and curves with unrestricted curvature can be used to define the problem. Nodal distribution is controlled by sophisticated interpolation and smoothing methods including multi-linear interpolation, transfinite interpolation, and elliptic solvers. TrueGrid's parameterization and batch capabilities can be used to create template input files. These files allow simple variations in geometry to be remeshed in minutes. In addition, TrueGrid's graphical user interface makes it easy to assign boundary and initial conditions, constraints and loads for a large number of simulation programs.

FLUENT users can achieve more accurate simulation results in less time by using the TrueGrid preprocessor. The innate superiority of using the projection method allows TrueGrid to import IGES geometry with no need for clean up. In addition, sophisticated smoothing and interpolation algorithms allow you to capture the most subtle boundary layer effects with the least computational effort. Fluid-structure interaction is easily represented with embedded meshes. And, at the end of every session, a user readable flat ASCII file is generated which can then be edited and re-used as a parameterized batch input file, providing automatic hexahedral grid generation.
