Date: March 22, 2021
Subject: Wayne Cowell (1926 - 2021)

Dr. Wayne Cowell, a member of the Mathematics and Computer Science
Division at Argonne National Laboratory for most of his professional
life, passed away February 24, 2021.  During that time he made a
lasting impact on computational science and on the scientists around
him.

In 1971 Wayne convinced the National Science Foundation to fund the
National Activity to Test Software (NATS) project between Argonne and
two universities: Stanford and the University of Texas at Austin. The
plan was to produce a set of subroutines with a uniform style and
naming convention. The subroutines would be based on the best
available algorithms, implemented at Argonne, and distributed to test
sites. Once the testing was completed, the subroutines were certified
as being robust, reliable, and portable. These ideas were new in 1971.

The NATS project produced the EISPACK and FUNPACK packages. The
success of this project laid the groundwork for Argonne's reputation
as a center for the development of high-quality numerical software.

Wayne is remembered as a kind, considerate colleague and a promoter of
mathematical software by the visitors to Argonne. His success in
promoting collaboration between Argonne and other research
institutions was key to the development of mathematical software.

Wayne edited the book "Sources and Development of Mathematics
Software" that details many of the lessons learned during the early
years.  If you want to know more about Wayne's work google "Oral
History Wayne Cowell".

level. The theoretical portion will consist of the following three
mini-courses, which will be accompanied by exercise sessions:

- Stationary Methods and Multiphysics (Hamdi Tchelepi and Felix Kwok)
- Domain Decomposition Methods (Victorita Dolean)
- Multigrid Methods (Scott MacLachlan)

In addition, there will be seminar talks on advanced techniques and
applications by four invited speakers (Andrea Franceschini, Louis
Poirel, Carmen Rodrigo and Julien Salomon). All lectures will be given
in English. The summer school is free of charge, but prior
registration is required. To register and to find out more about the
summer school program, please visit our website at

Multiscale Methods for the Inverse Estimation of Effective Properties
of Poroelastic Tissue", a collaboration between the WIAS and the Chair

We call for applications for a Ph.D. position in the junior research
group for dynamical systems within the cluster of excellence
simulation technologies (SimTech) at the University of Stuttgart,
Germany, to work in the area of energy-based models.

Research activities of this Ph.D. position focus on the novel methods
to construct physically meaningful models solely from data using the
framework of port-Hamiltonian systems. The research tackles a
fundamental question: to guarantee the physical behavior of a coupled
dynamical system learned from data and (partial) differential
equations derived from first-principles. To ensure an efficient
evaluation of the resulting systems, the candidate will develop and
implement structure- preserving model-order reduction methods. The
research results will contribute to a new data-integrated simulation
paradigm prevalent in future high-tech initiatives in systems
engineering, such as the digital twin methodology.

Research activities of this Ph.D. position focus on the development
and analysis of time-integration schemes for coupled partial
differential equations (PDEs) that describe the deformation of a
porous media saturated by fluid networks. The research results will
