I hold a doctorate degree in
Engineering Mechanics from Virginia
Polytechnic Institute and State University. I had worked
J.N. Reddy who is an internationally acknowledged leader in Finite
Element Theory. Dr. Reddy is currently at Texas A&M.
I have about 10 years
experience in developing advanced FE theory formulations and software.
My experiences cover composite structures (plates and shells), building
structures (under static and dynamic/earthquake loading), multiphysics
FEA and mechanical
I am also very much interested
in the software aspect of FEA. Numerical solution algorithms,
large-scale parallel and distributed computing, web-based technologies,
COM/DCOM, Object-oriented programming techniques,
computational mechanics interest me.
I have also been teaching Principles
and Practices of FEA to practicing electrical, mechanical,
structural, industrial, geo-technical and bio-medical engineers in the
San Diego area at UCSD
(University Of California, San Diego) extension. My students
have come from leading San Diego area firms such as Qualcomm,
Kyocera, SAIC, Honeywell, General Dynamics, TRW and the Navy.
The MEMS Course is scheduled to
be given twice in 2001 also.

I have been
using ANSYS for approximately 17 years and have experience with
nearly every solution capability that the program offers. I am
particularly experienced at performing electromagnetic, electrostatic,
and coupled field solutions, and have taught the ANSYS electromagnetics
course perhaps half a dozen times.
Papers I have
written which have been published in ANSYS Conference proceedings
Large Deflection Coupled Electrostatic-Structural Analysis”
“Transient Analysis of a Permanent Magnet Bearing”
Induction Heating Simulation of a Helical Gear”
Modeling of Unexploded Ordnance Using ANSYS”
I am also
proficient in the use of ANSYS/LS Dyna explicit dynamics, and wrote a
specialized UIDL (ANSYS menu) interface which simplifies the setup and
execution of drop test simulations. I wrote a 3 day training coarse on
the use of ANSYS in simulating residual stresses produced by packaging.
This course was taught in Hsinchu, Taiwan, at ANSYS Inc., and at
Silverado Software and Consulting. Additionally, I created and presented
a coupled fields solution capabilities presentation in Tokyo.
I did my
first MEMS force versus voltage analysis in 1993 - presented methodology
at the 1994 ANSYS Conference in Pittsburgh, PA. This was fairly involved.
ANSYS had no electrostatic elements at the time (I used steady state current
conduction elements analogously). Electrostatic force evaluation,
subsequent transfer to the structural model, displacement updates to
the electrostatic analysis, files handling all had to be done with macros
(it's all pretty much automatic these days).
things were slow in this arena for quite some time until 1996 or so, when a few
scattered individuals became interested in applying the methodology.
Then we did quite a lot of consulting for a micro mirror customer in
1998 or 1999 here at CSI. This was before ESSOLV and mesh morphing were
added to ANSYS (the current release of ANSYS at the time was 5.5 - the
MEMS initiative came at release 5.6). We used structural elements
electrostatic domain between electrodes to accomplish
"morphing" (I still use
this technique from time to time).
The past year
or so we've not been asked to do consulting so much as demonstrate
ANSYS to prospects and training.
I guess you
could say this: my main responsibilities at Collaborative Solutions, Inc
(CSI) are to train and provide
technical support to multidisciplinary and coupled fields ANSYS users and to
perform electromagnetic and coupled field simulations on a consulting
