Subject: deal.II version 9.7 release
Version 9.7.0 of deal.II, the object-oriented finite element library
awarded the J. H. Wilkinson Prize for Numerical Software and the
SIAM/ACM Prize in Computational Science and Engineering, has been
released. It is available for free under an Open Source license from
the deal.II homepage at
https://www.dealii.org/
The major changes of this release are:
- Three new tutorial programs, showing how to deal with non-local degrees
of freedom (step-93), matrix-free CutFEM methods (step-95), and curl-curl
problems (step-97).
- The introduction of an optimized MappingP1 class for affine mappings
on simplex elements
- Improved portability for matrix-free operations through the use of Kokkos
- Task-based programming support is now based on the Taskflow library, in
addition to the existing support via the Threading Building Blocks (TBB).
- Many updates to external libraries, including to Kokkos, MUMPS, PSBLAS,
Magic Enum, and ArborX, as well as to Trilinos' Tpetra stack.
- deal.II can now build C++20-style modules.
More information about changes can be found in the release preprint at
https://www.dealii.org/deal97-preprint.pdf.
The main features of deal.II are:
- Extensive documentation and 88 working example programs
- Support for dimension-independent programming
- Locally refined adaptive meshes and multigrid support
- A zoo of different finite elements
- Built-in support for shared memory and distributed parallel computing,
scaling from laptops to clusters with 300,000+ of processor cores
- Interfaces to Trilinos, PETSc, SUNDIALS, UMFPACK and many other external
software packages
- Input and output for a wide variety of meshing and visualization platforms.

Computational Bodily Fluid Dynamics
Models, Algorithms and Applications
Eleuterio F. Toro
University of Trento, Italy
Springer Nature, August 2025
This book focuses on mathematical models for the integrated fluid dynamics
of bodily fluids in humans, including arterial blood, venous blood, interstitial
fluid, and cerebrospinal fluid. Emphasis is placed on a holistic approach by
integrating all major fluid compartments throughout the human body to
replicate their functional and anatomical connectivity. Many of the models
and methods presented can be extended to other systems, such as the
lymphatic and urinary systems.
The book is based on two master’s courses, a PhD Winter School offered at
the University of Trento, and lectures given over the years at universities in
several countries. The content is organized into 21 chapters, divided into four
parts: I: Elements of Fluid Physiology; II: Equations, Analysis, and Exact
Solutions; III: Computational Algorithms for Partial Differential Equations
IV: Major Cardiovascular Diseases
This book can be used for teaching computational methods for bodily fluid
dynamics to master’s and PhD students, or to advanced undergraduate
students in academic departments such as engineering, mathematics,
physics, computer science, biology, and medicine. It may also be useful to
researchers in universities and research laboratories working in fields such as
human fluid physiology, mathematical modelling of bodily fluids,
computational biofluid dynamics, numerical analysis of partial differential
equations, and cardiovascular diseases.

The Mid-Atlantic NA Day 2025 will take place at
Temple University, Philadelphia on Friday 14 November 2025.
The purpose of this one-day meeting is to provide a forum for
Graduate Students and Postdoctoral Fellows, i.e.,
researchers and practitioners at the very beginning of their careers,
from the Mid-Atlantic region, to exchange ideas in numerical analysis,
scientific computing, computational mathematics, and related application areas.
More established scientists are encouraged to attend as well.
Talks start at 10 AM to facilitate same-day travel.
Keynote speaker: Mayya Tokman, University of California, Merced
Title: Why, What and How of Exponential Integration
Please encourage your students and postdocs to attend (or
yourself if you are a postdoc, or if you want to listen to
the grad students and postdocs).
Abstract submission deadline is 17 October 2025.
There will be no registration fee, but we ask participants
to please register.

Subject: MATHRIX Assistant Professorships at the University of Münster
The Cluster of Excellence Mathematics Münster: Dynamics – Geometry –
Structure at the University of Münster invites applications for two
MATHRIX Assistant Professorships in Mathematics (salary level W1)
One of the positions will be filled in an area of theoretical, and one
in an area of applied mathematics. The professorships are for three
years with the possibility of an extension for another three years
upon positive evaluation.
The professorships should contribute to gender equality within the
mathematical sciences. Applications are particularly welcome if they
strengthen, complement and/or connect existing research topics of the
Cluster.
Application deadline: September 30, 2025

Subject: 2026 Alvarez and Hopper Postdoctoral Fellowships at Berkeley Lab
The Computing Sciences Area (https://cs.lbl.gov/) at Lawrence Berkeley
National Laboratory (https://www.lbl.gov) is now accepting
applications for two distinguished postdoctoral fellowships in
Computing Sciences: the Luis W. Alvarez Postdoctoral Fellowship and
the Admiral Grace M. Hopper Postdoctoral Fellowship.
The successful candidates will participate in research activities in
computer science, mathematics, data science, or any computational
science discipline of interest to the Computing Sciences Area and
Berkeley Lab. Alvarez Fellows apply advances in computer science,
mathematics, computational science, data science, machine learning or
AI to computational modeling, simulations, and advanced data analytics
for scientific discovery in materials science, biology, astronomy,
environmental science, energy, particle physics, genomics, and other
scientific domains. Hopper Fellows concentrate on the development and
optimization of scientific and engineering applications leveraging
high-speed network capability provided by the Energy Sciences Network
or run on next-generation high performance computing and data systems
hosted by the National Energy Research Scientific Computing Center at
Berkeley Lab.
Since its founding in 2002, Berkeley Lab’s Luis W. Alvarez
Postdoctoral Fellowship (https://go.lbl.gov/alvarez) has cultivated
exceptional early career scientists who have gone on to make
outstanding contributions to computer science, mathematics, data
science, and computational sciences. The Admiral Grace Hopper
Postdoctoral Fellowship (https://go.lbl.gov/hopper) was first awarded
in 2015 with the goal of enabling early career scientists to make
outstanding contributions in computer science and high performance
computing (HPC) research.
For consideration, applications are due October 24, 2025. For more
information, please visit https://go.lbl.gov/2026.

You have a master's degree in applied mathematics, computational
science or a compatible STEM subject. You can demonstrate a solid
foundation in programming through either academic projects or
otherwise. Knowledge or experience in at least one of these
methodological fields is an advantage: mathematical modeling,
stochastic simulation and uncertainty quantification. Further, prior
experience in C++ and/or CUDA is a plus. We aim for a starting date
between September 2025 and February 2026.
