TrueGrid®

Overview

As users develop complex models, it is critical to have model generation software that produces high fidelity meshes with computational accurate elements, that is, elements whose geometry have acceptable aspect ratios that ensure accurate results. In order to meet this requirement, the TrueGrid mesh generation software was selected. TrueGrid uses projection algorithms that produce computational grids with well formed quadrilaterals and hexahedrons. a license for one seat was obtained from XYZ Scientific Applications, Inc. (the developer of TrueGrid). TrueGrid has all the ingredients needed for both Computational Structural Mechanics and Computational Fluid Dynamics meshing.

Current TRACC Applications

Researchers at TRACC are using TrueGrid to develop finite element models for bridge superstructures, supporting piers with footings and the scour pit in the riverbed. The work is aimed at determining the stability of the bridge for profiles of the scour pit with different depths
