Subject: J D Lambert (1932 - 2018)

It is with great sadness that we report the death of Jack Lambert,
Emeritus Professor of Numerical Analysis at the University of
Dundee. After three years in the Royal Naval Scientific Service, Jack
became a PhD student of Ron Mitchell's at the University of St
Andrews, completing his degree while also employed as a Lecturer. He
was one of the organisers of the numerical analysis conference at the
University of St Andrews in 1965 which is regarded as the first of the
biennial series of conferences which moved to Dundee in 1969, and
continues now at the University of Strathclyde.

Jack joined Ron Mitchell in Dundee in 1967, after a brief period at
the University of Aberdeen. His research interests lay in the
numerical solution of ordinary differential equations on which he
supervised many PhD students and authored two highly-regarded text

As well as research and teaching, Jack served as Head of Department
and Dean of the Faculty of Science and Engineering. He was elected a
Fellow of the Royal Society of Edinburgh in 1976.

Jack was a very warm man and splendid company at all times. He had a
wise head and was a fount of sound advice. He will be sadly missed by
his former colleagues and many friends worldwide, and we are sure they
would ant to join us in passing on our condolences to his wife Heather
and their sons Ian and Roddy.

Subject: ScalFMM Version 1.5.1

We are pleased to announce the release 1.5.1, as an open-source
software, of ScalFMM, a task-based scalable kernel independent fast
multipole method.

The design of the library separates the FMM-core (octree management,
data structure, parallelism, ...) and the kernels that allow you to
easily introduce new kernels.

- Kernel independent method based on interpolation. We provide as well
as a method based on Chebyshev and equispaced grid points.
- Scalar and tensorial kernels
- Different implementations for Poisson kernel are available :
spherical expansion with rotation and BLAS optimizations, Chebyshev
points and equispaced grid points.
- Shared memory (OpenMP and StarPU (runtime system) and hybrid
distributed/shared memory (MPI/OpenMP)

The project Home page is
where instructions for obtaining the source code are
provided. Installation instructions and a User's Guide are also

Contributions and feedback from users are welcome.

Subject: Short Course on Peridynamics at WCCM, USA, Jul 2018

Short Course on Peridynamics
13th World Congress on Computational Mechanics (WCCM 2018)
July 22-27, 2018, New York City, NY

A short course on the Peridynamic Theory of Solid Mechanics will be
held at the upcoming 13th World Congress on Computational
Mechanics. The short course will review the peridynamic theory, and it
will discuss various applications as well as related modeling and
computational aspects. Students, postdocs, as well as early-career
and senior researchers are welcome to participate. The short-course
description is given below.

Title: Peridynamic Theory of Solid Mechanics: Modeling, Computation,
and Applications

- Dr. John Foster (
The University of Texas at Austin
- Dr. David Littlewood (
Sandia National Laboratories
- Dr. Pablo Seleson (
Oak Ridge National Laboratory

Peridynamics is a nonlocal reformulation of classical continuum
mechanics, based on integral equations, suitable for material failure
and damage simulation. In contrast to classical constitutive
relations, peridynamic models do not require spatial differentiability
assumptions of displacement fields, leading to a natural
representation of material discontinuities such as
cracks. Furthermore, peridynamic models possess length scales, making
them suitable for multiscale modeling. This course will provide an
overview of peridynamics, including its mathematical, computational,
and modeling aspects. The course will also review advanced research
topics and software in peridynamics, and it will include a hands-on
tutorial on 3D simulation of solid mechanics problems.

Subject: Numerical Computing in Algebraic Geometry, Germany, Aug 2018

This message is to advertise the upcoming Summer School on Numerical
Computing in Algebraic Geometry to be held at MPI MiS Leipzig, 13-17
August 2018.

The aim of this summer school is to provide insight into numerical
methods in algebraic geometry. Unlike traditional summer schools,
special emphasis is put on the application and usage of software:

- Bertini
- Tensorlab

The intention is to familiarize participants with the techniques and
provide hands-on experience with how they can be applied to
problems. As such, the summer school will feature software sessions in
lieu of traditional exercise sessions.

The lectures will be given by:
- Jonathan Hauenstein (University of Notre Dame, Indiana)
- Pablo A. Parillo (Massachusetts Institute of Technology)
- Nick Vannieuwenhoven (KU Leuven, Belgium)

Subject: Postdoc Position, Numerical Analysis, KTH, Stockholm

We are announcing a two-year postdoc position in numerical analysis at
KTH in Stockholm. The postdoc will work on a collaborative project
with Prof Bjorn Engquist at UT Austin, "Multiscale algorithms for
effective approximation of interfaces in fluid flows".

The work "interfaces" in this title includes e.g. interfaces between a
region of clear fluid and a porous structure with small scale
features. The essential idea is to apply efficient and accurate
numerical methods based on integral equations for microscale
simulations in small local domains near the interfacewith
micro-structure, coupled with macroscale methods away from the
interface through effective interface conditions.

The starting date is flexible, and we encourage candidates to apply
and state a preferred starting date between Aug 2018-Jan 2019.

The deadline for application is May 2, 2018.
