Niklas Andersson

Universitetslektor at Department of Applied Mechanics, Fluid Dynamics

My main interests are simulation of compressible flows, numerical techniques for computational fluid dynamics, modal analysis of flows using eigenmode extraction and simulation of flow induced noise. The major part of my research regards topics related to propulsion and aeronautics. I am the main developer of G3D::Flow, a massively parallel CFD code for simulation of compressible and incompressible flows. G3D::Flow is written in C++ and utilize solvers and distributed data types available in the open-source PETSc library.
