Blood
Flow Analysis Improves Stent-Grafts
 By Dr. Clement Kleinstreuer and
Zhonghua Li,
Biomechanical Engineering Research
Group, North Carolina State University
One of the more intriguing challenges in modern
medicine is the repair of abdominal aortic aneurysms
using stent-grafts: tubular wire mesh stents interwoven
with a synthetic graft material. The device is guided
into place through a small incision in the groin and
then propped open in the aorta, thus reinforcing the
damaged area of the artery. For reasons that were not
well understood until recently, however, some
stent-grafts move out of place. This migration may again
expose the weakened aortic wall to relatively high blood
pressure, potentially leading to sudden aneurysm rupture
and death.

ANSYS
for Virtual Surgery
 FEA is a valuable tool
that aids doctors in orthopedic
operations.
By András Hajdu and Zoltán
Zörgö
Institute of Informatics, University of
Debrecen, Hungary
Analysis, imaging and visualization technologies are
being applied increasingly in medical applications,
particularly in evaluating different approaches to
surgery and determining the best ways to proceed in the
operation. In this growing field, one of the primary
focuses of our work applies finite element analysis to
orthopedic surgery: specifically, the specialized area
of osteotomy, where bones are surgically segmented and
repositioned to correct various deformities. We chose
ANSYS for this work because of the reliability and
flexibility of the software in handling the irregular
geometries and nonlinear properties inherent in these
materials.

Upcoming
ANSYS Conferences
Continuing what avid ANSYS users consider a CAE
tradition, preparations are underway around the
world for the 2004 ANSYS Users Conferences for
the Fall. These events bring together engineers and
analysts from all disciplines of computer-aided
engineering.
These conferences are a unique opportunity for
attendees to learn about ANSYS’ strategy for the future
of engineering design simulation and analysis. Plus,
attendees have the chance to gain an understanding of
ANSYS, ICEM CFD and CFX, and how the integration of
these technologies offers an unprecedented level of
capability in one solution.

Landmark in Simulation
 by Nick Waterson, Mott
Macdonald
The Maitreya
Project International is planning to build one of
the largest statues of the Buddha in the world. The
statue, with a height of 152m and a design life of 1000
years, is to be located in northern India. Mott
Macdonald has been acting as consultant for a number of
aspects of the design as well as the project management.
The unusual nature and size of the structure mean that a
number of advanced analysis techniques, including
computational fluid dynamics, are required to overcome
the many design challenges. During the preliminary
design phase, one key issue to be addressed was the
effect of extreme wind loads on the structure. It was
decided to use a CFD approach for the initial
determination of these loads, to be backed up by
wind-tunnel testing and further CFD studies later in the
project.
