Position and Responsibilities

Dr. Holtz is a Senior Development Engineer, supporting real time simulation and vehicle dynamics R&D at Realtime Technologies. His responsibilities include:
  • Developing multi-body vehicle models using SimCreator

  • Developing and implementing track models, off-road and on-road tire models

 

Experience

Before joining Realtime Technologies, Dr. Holtz served from 2000 to 2005 as Research Scientist at NADS, National Advanced Driving Simulator, shared-use research facility operated by The University of Iowa, The NADS was created to conduct research which will help save lives, reduce the costs of vehicle crashes, and lead to better and safer vehicles, roadways, and drivers.

At NADS, he was responsible for developing and maintaining multibody dynamics software used for real time operator-in-the-loop vehicle simulations in addition to creating and validating new vehicle models for use at NADS. 

For three years from 1997 to 2000, Dr. Holtz was Senior Development Engineer at LMS CADSI, the Mechanical Simulation Technologies Division of LMS International.  He was responsible for implementing new capabilities and improving the performance of the commercial software package DADS.. Dr. Holtz implemented new capabilities such as:

  • Advanced friction modeling.
  • Preload analysis.
  • Efficient sparse matrix algebra.
  • Improved redundant constraint identification algorithms.
  • Interactive simulation.

At LMS CADSI Dr. Holtz was also involved in developing implicit integration techniques for differential-algebraic equations, flexible body dynamics and static analysis.

From 1988 to 1989 Dr. Holtz held the position of Associate Engineer at Douglas Aircraft Company.  Dr. Holtz worked with the wing structural design group and the propulsion systems design group on the C-17 military transport aircraft.

Dr. Holtz also has experience teaching college-level courses at The University of Northern California, Petaluma, Cal., North Dakota State University in Fargo N.D., and The University of Iowa in Iowa City, Iowa.
