Dr. Keith Meintjes & Dr. Ken Versprille


Keith Meintjes, Ph.D., Executive Consultant, Simulation, CIMdata

Dr. Keith Meintjes has over 35 years of experience in the development and application of simulation tools to transform product development. His achievements include novel methods for combustion simulation, patents for engine design, and strategic planning for the world’s largest commercial HPC facility.

Keith joined CIMdata when they acquired CPDA, where he was Research Director for CAE and managed CPDA’s Design/Simulation Council. Previously, he spent nearly 30 years at General Motors.

At GM he was responsible for the engineering requirements for GM’s Global CAE IT infrastructure and was named Senior Technical Fellow. At GM Powertrain he held strategic, planning, and management positions, to embed simulation tools in the powertrain product development process. Earlier, at the GM Research Laboratories, he developed thermodynamic and CFD simulation models for engine performance and combustion, and was instrumental in GM’s acquisition of a Cray supercomputer.

Keith holds BSc and MSc degrees in Mechanical Engineering, with a specialty in Aeronautics, from the University of the Witwatersrand, and an MA and Ph.D. from Princeton University.


Ken Versprille, Ph.D., Executive Consultant and Practice Manager, Social Product Development & Collaboration

Dr. Ken Versprille has over 35 years of experience in the application of computer-based solutions for engineering and manufacturing. He joined CIMdata after 16 years heading the Design Creation and Validation service at CPDA. His research spans geometric design, design collaboration and automation, PLM standards and openness, and the integration of CAD across PLM applications.

During 15 years at Computervision, Dr. Versprille became the equivalent of CTO, and was R&D Vice President of core applications. He was a lead architect of the CADDS 4 product, with responsibility for the initial design of Computervision’s 3D graphics system. As General Manager of CV-Doors, he led the group that introduced and managed the CAD industry’s first geometric kernel business.

Dr. Versprille received a BS in Mathematics from the University of New Hampshire. His MS and Ph.D. in Computer Science are from Syracuse University. Dr. Versprille is recognized for publishing the first description of NURBS, the mathematical curve-and-surface formulation, now an international standard in CAD and Computer Graphics. In 2005 he received a Lifetime Achievement Award by The CAD Society.

Dr. Ted D. Blacker, Manager, Simulation Modeling Sciences, Sandia National Laboratories

Dr. Ted Blacker began his career at Sandia Labs working as a computational analysts performing FEA simulations in solid mechanics and structural dynamics. He was drawn to research in meshing to solve the model building bottleneck in the analysis process. His discovery and development of the Paving algorithm provided the first all-quad general meshing tool, led to several patents and an eventual R&D 100 award. Further work in hexahedral meshing resulted in the establishment of the CUBIT project and the ongoing International Meshing Roundtable (now in its 25th year). He eventually left Sandia to work in private industry on a technology transfer leave of absence. Dr. Blacker worked for both FDI and FLUENT, leading the GAMBIT project development (a general geometry and meshing tool). He eventually returned to Sandia as a manager and has continued his research focus. He has published extensively and served on temporary assignment to the DoD CREATE program in Washington DC. Dr. Blacker currently manages 1) the meshing and geometry research team (CUBIT), 2) a new team developing topology optimization for additive manufacture (PLATO), and 3) a team providing high performance computing infrastructure (Sierra Toolkit) for the SIERRA code base. Dr. Blacker obtained his BS and MS in CE from BYU, followed by a PhD from Northwestern University in Theoretical and Applied Mechanics.
