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.
