Robert Rainsberger spent his earliest 4 years in the U.S. Air Force before entering the University of Illinois to earn his B.S. in mathematics in 1979. He was then employed by Lawrence Livermore National Laboratory for two years as a computer scientist before entered the University of California, Berkeley. In 1988 he received his Ph.D in mathematics. After completing his Ph.D., Dr. Rainsberger returned to Lawrence Livermore National Laboratory to continue working on 3D hexa mesh generation. During this same period, Dr. Rainsberger contracted to Control Data Corporation to develop the first versions of ICEM CFD. In 1991, Dr. Rainsberger founded XYZ Scientific Applications, Inc. where he remains the principle code developer of TrueGrid, President, and CEO of the corporation. Dr. Rainsberger has 30 years experience in high end mesh generation and has contributed key ideas in TrueGrid. He developed the projection method, unique to TrueGrid. He extended the method to automatically compensate for inaccurate geometry typically imported from IGES. He also developed the multi-block structured method of mesh generation used today for the best quality hexa meshes. He developed all six of the interpolation and elliptic smoothing methods employed in TrueGrid. In particular is the ability to smooth a mesh on a non-smooth surface. He extended the projection method to polygon surfaces typically extracted from CAT scans or MRI data used in the biomechanics field. Dr. Rainsberger is also responsible for implementing the many parametric features in TrueGrid. Dr. Rainsberger has authored most of the TrueGrid and related manuals. In 2005, Dr. Rainsberger solved Schneiderís open problem (unpublish). This led to a new provable method of automatic hexa mesh generation. Dr. Rainsberger has published numerous papers in mesh generation, but the majority of his work remains a Trade Secret of the corporation.
