3D Hex and 2D Quad Meshes With TrueGrid®, users have complete control over the design of their mesh. All meshes are composed of block structured hex or quad grids. TrueGrid® has an integrated library of element shapes which include 3D hex, prism, pyramid, and tet bricks; 2D quad and triangular shells; 1D beams; and special elements such as springs, dampers and point masses. 3D, 2D, and 1D elements can be linear or quadratic.

In addition to generating the mesh for these simulation codes, TrueGrid® has pre-processing applications as well. TrueGrid® generates control parameters, options, loads, contact surfaces, and conditions. Element type, section, and material properties can also be specified. View larger image Structure-Fluid Interface TrueGrid®'s block structured approach and projection method allows users to create a mesh for either fluids or structures. In addition, this technique makes it easy to build a structure that matches the faces of a fluid, forming a perfect interface between fluids and structures. This method allows TrueGrid® to embed one mesh inside another. View larger image Features for Assemblies TrueGrid®'s assembly features allow users to build complex models. The block boundary feature ensures exact interface between parts. Transitioning between dissimilar parts is automatic and guarantees the same block boundary precision. Parts are easily replicated to form complex assemblies from simple components. The include feature can be envoked to re-use template parts.
