Subject: Ed Oliver, former ONRL computing director, dies

The following is from ORNL Today:

Ed Oliver, who led Oak Ridge National Laboratory's early efforts in high
performance computing in the 1990s, died Tuesday in Washington, D.C.,
following an illness.

Oliver founded and directed ORNL's Office of Laboratory Computing in the
1990s. He recognized the scientific promise of high-performance computing
early on and was instrumental in establishing ORNL's High Performance
Computing Research Center, which featured the Intel Paragon, the first of
ORNL's state-of-the-art supercomputers.

"It was Ed Oliver's vision that Oak Ridge National Laboratory would one day be
the world leader in scientific computing and its application to solving some
of the most compelling problems that face humanity. He always had high
expectations of the promise of supercomputing and therefore had high
expectations of ORNL," says Thomas Zacharia, ORNL Associate Laboratory
Director for Computing and Computational Science.

Oliver went from ORNL to lead the Department of Energy's Office of Advanced
Scientific Computing Research, which laid the groundwork for the DOE Office of
Science's current leadership role in scientific computing.

A former chief scientist at the Air Force Research Laboratory, Carl Edward
Oliver was a native of Anniston, Ala., and was a University of Alabama alumnus.

Subject: PhD position in Computational Mechanics at LAMCOS - INSA de Lyon

Subject: Multi physics & multi phase numerical simulation for lubrication models
Lubrication of machine elements represents nowadays important environmental,
economical and technical issues. Minimization of friction losses
(environmental and economical aspects) and film thickness reduction (technical
aspect) in lubricated devices lead to new operating conditions and among them
the early lubricating film breakdown or the presence of multi phase flow.
We propose to develop a new numerical approach of lubricated contact modeling
based on stabilized finite elements. This approach requires both the coupling
between several equations (Reynolds (a simplified form of the fluid dynamics),
Elasticity, Energy and those describing the physical behavior of the fluid)
and the implementation of efficient numerical methods.
Among the cases to deal with, the coupling between the exit part of a contact
(where the fluid film rupture occurs) and the inlet zone of the following
contact offers the challenge of the entrainment of a gaseous phase to be
modeled. Furthermore, the simultaneous resolution of thin film mechanics and
fluid thermodynamics equations could bring supplementary numerical difficulties.
The overall objective is to develop new numerical tools (C/C++ developments)
and to obtain qualitative validation from tests performed on in-house devices
and conducted in collaboration with our technical staff.
SKF - Engineering & Research Centre (based in the Netherlands) supports this
research activity since the early phase in 2005.

Mécanique et d’Acoustique

Basic skills in mechanical engineering and/or computational mechanics and
numerical analysis are required. A strong interest for programming techniques
(object-oriented, C/C++) is also required. Some background in Tribology and
Thermodynamics may be an asset. The candidate is expected to be motivated and
pro-active in generating ideas and hypotheses. A previous experience in
programming numerical methods and algorithms would be appreciated.
Good knowledge and communication skills in the English language are highly
desired. The candidate should be graduated at the Master level at the start of
the thesis, planed in early October 2008.
