Within the next two weeks, we expect to transition over the NA Digest list. The rollout has been smooth for other lists, so we expect no disruptions. You may receive one pair of emails (to the old and new services) to confirm functionality. ------------------------------------------------------- From: Christian Klingenberg christian.klingenberg@uni-wuerzburg.de Date: May 31, 2026 Subject: Phil Roe passed away Phil Roe passed away on April 26, 2026, just over a week shy of his 88th birthday. Phil's strong will, that lasted until the end of his life, scientifically is reflected in his independent and unique way of thinking. An illustration is his view late in life of 2 and 3-dim compressible Euler flow as a splitting between nonlinear advection and the spread of information (which he called acoustics) in this moving framework. An early incarnation of this insight (where to distribute the fluctuations to, in a moving frame) in one space dimension was his Riemann solver published in 1981. After this Roe solver his attempt to find a multi- dimensional analogue lead him first to pursue residual distribution. When Phil was in his mid-seventies these thoughts culminated in him devising his Active Flux concepts - ideas that are now inspiring the work of various groups mainly in Europe. Of course there were many more important contributions of his, which he typically shared generously. An example are his contributions to computing MHD (his scaling of the eigensystem; noticing with Powell the usefulness of Godunov's symmetrization). His British pragmatism coupled with deep insight lead to successful tools in computational practice that really worked. Phil Roe made a profound and enduring influence on the computational fluid mechanics community. He has been an inspiration for many, we shall deeply miss him. ------------------------------------------------------ From: Eda Oktay oktay@mpi-magdeburg.mpg.de Date: June 05, 2026 Subject: GAMM ANLA Annual Workshop, Sept, 2026, Magdeburg (Germany) REMINDER FOR PARTICIPATION and ABSTRACT SUBMISSION: 26th Annual Workshop of the GAMM Activity Group on Applied Numerical Linear Algebra (ANLA) will be held on September 3-4, 2026 in Magdeburg Germany.
