High performance Python for direct numerical simulations of turbulent flows
Mikael Mortensen, Hans Petter Langtangen
Direct Numerical Simulations (DNS) of the Navier Stokes equations is an invaluable research tool in fluid dynamics. Still, there are few publicly available research codes and, due…
Unified Framework for Finite Element Assembly
Martin Sandve Alnæs, Anders Logg, Kent-Andre Mardal +2
At the heart of any finite element simulation is the assembly of matrices and vectors from discrete variational forms. We propose a general interface between problem-specific and g…
A FEniCS-Based Programming Framework for Modeling Turbulent Flow by the Reynolds-Averaged Navier-Stokes Equations
Mikael Mortensen, Hans Petter Langtangen, Garth N. Wells
Finding an appropriate turbulence model for a given flow case usually calls for extensive experimentation with both models and numerical solution methods. This work presents the de…
Simplifying Parallelization of Scientific Codes by a Function-Centric Approach in Python
Jon K. Nilsen, Xing Cai, Bjorn Hoyland +1
The purpose of this paper is to show how existing scientific software can be parallelized using a separate thin layer of Python code where all parallel communication is implemented…
Pulse-induced acoustoelectric vibrations in surface-gated GaAs-based quantum devices
S. Rahman, T. M. Stace, H. P. Langtangen +2
We present the results of a numerical investigation which show the excitation of acoustoelectric modes of vibration in GaAs-based heterostructures due to sharp nano-second electric…
A finite element analysis of a silicon based double quantum dot structure
S. Rahman, J. Gorman, C. H. W. Barnes +2
We present the results of a finite-element solution of the Laplace equation for the silicon-based trench-isolated double quantum-dot and the capacitively-coupled single-electron tr…
