Grid Generation Now available, TrueGrid version 2.2 delivers major enhancements and additions to its already extensive list of capabilities. Below are only a sample of what is new.

Extensive enhancements and additions have been added to the output features for many analysis packages. Packages enhanced include LSTC DYNA (including thermal materials and DATABASE extensions), MSC NASTRAN (including rigid bodies material types), ANSYS (including materials, analysis options and cross section data), ABAQUS (fixed formats are no longer used), and NIKE3D (now includes 20 noded brick elements and sliding interfaces with 8 noded segments). Further, TrueGrid now supports Noran Engineering, Inc. NASTRAN and TOPAZ3D version 2000.

Input for IGES files has been extended to support singular subfigure and FEM elements. New entities include nodes, many of the element types, and tabular data. In addition, the nodes and elements in an LSTC DYNA keyword input file can be read and placed in the TrueGrid data base.

The Uniform smoothing smoothing is now available for faces. In addition, Uniform smoothing can be performed with Neumann boundary conditions.

Major advancements have been added to the transition block boundary command. Transitional elements are available in two directions at one interface. In addition, intermediate partitions are now allowed on the slave side of the transition. Transition block boundaries now work with both linear and quadratic elements.

Also noteworthy are commands which: increase the mesh density uniformly in all 3 directions by an scale factor, simplify graphical slicing, extend diagnostic measures, display multiple labels and conditions, define functions usable in any expression or equation, and polygons sets from polygon surfaces and surface definitions from polygon sets (for sorting out and splitting complex polygon surfaces).
