High-order finite element method for atomic structure calculations
Ondřej Čertík, John E. Pask, Isuru Fernando +5
We introduce \texttt{featom}, an open source code that implements a high-order finite element solver for the radial Schrödinger, Dirac, and Kohn-Sham equations. The formulation acc…
The State of Fortran
Laurence Kedward, Balint Aradi, Ondrej Certik +14
A community of developers has formed to modernize the Fortran ecosystem. In this article, we describe the high-level features of Fortran that continue to make it a good choice for…
Toward Modern Fortran Tooling and a Thriving Developer Community
Milan Curcic, Ondřej Čertík, Brad Richardson +5
Fortran is the oldest high-level programming language that remains in use today and is one of the dominant languages used for compute-intensive scientific and engineering applicati…
Review of the First Charged-Particle Transport Coefficient Comparison Workshop
P. E. Grabowski, S. B. Hansen, M. S. Murillo +42
We present the results of the first Charged-Particle Transport Coefficient Code Comparison Workshop, which was held in Albuquerque, NM October 4-6, 2016. In this first workshop, sc…
The - and -versions of the virtual element method for elliptic eigenvalue problems
O. Certik, F. Gardini, G. Manzini +2
We discuss the - and the -versions of the virtual element method for the approximation of eigenpairs of elliptic operators with a potential term on polygonal meshes. An appl…
The virtual element method for eigenvalue problems with potential terms on polytopal meshes
Ondrej Certik, Francesca Gardini, Gianmarco Manzini +1
We extend the conforming virtual element method to the numerical resolution of eigenvalue problems with potential terms on a polytopal mesh. An important application is that of the…
