Computational Fluid Dynamics at the Institute of Fluid Mechanics following Codes are applied:
TAU
Flow Solver TAU is software system for the prediction of viscous and inviscid flows about complex geometries from the low subsonic to the hypersonic flow regime, employing hybrid unstructured grids. The TAU-Code is high efficient on parallel computers and is optimized for cache processors through specific edge colouring procedures. Parallelization is based on domain decomposition and the message passing concept using MPI.
While TAU is mainly used for complex aircraft-type configurations (including coupling to structure and flight mechanics codes) there exist also extensions which allow the simulation of re-entry flows, i.e. chemical reactions of air (or other gases) can be taken into account.
While TAU comprises modules for grid modification, namely the adaptation and the deformation module, it does not include grid generation. TAU can be used with both (block-) structured and hybrid unstructured grids composed of hexahedrons, prisms, tetrahedrons and pyramids. The first two element types are usually used in semi-structured layers above surfaces allowing for a better resolution of boundary layers. Tetrahedrons are used to fill the computational domain in a flexible way, allowing for local refinement without hanging nodes while the pyramids are needed for the transition between elements with quadrilateral faces and elements with triangular faces.

TRACE The Flow Solver TRACE is a system to calculate and investigate flows in turbomachinery.
TRACE is being developed at the Institute of Propulsion Technology at the DLR in Cologne.

HYDRA The Simulationprogramme HYDRA was developed at Rolls Royce in Derby (UK) and contains a Flow Solver as well as several Pre- and Post-Processing-Modules. HYDRA is applied to Flows in Turbomachinery.
NUMECA FINE/Turbo
UMECA FINE is a Flow Integrated Environment available for the simulation of internal, rotating, and turbomachinery flows, and this for all types of fluids. It integrates a fully hexahedral, highly automated grid generator, a visualization tool and advanced density-based numerical algorithms with local preconditioning.
FLUENT ANSYS Fluent software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. Special models that give the software the ability to model in-cylinder combustion, aeroacoustics, turbomachinery, and multiphase systems have served to broaden its reach.
Xfoil XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils.
It consists of a collection of menu-driven routines which perform various useful functions like viscous and inviscid analsysis of exiasting airfoils.

MISES The basic Funcionalities correspond to those of Xfoil, but MISES is applied to Turbomachineryflow.
