## Manuals and Guides

As an user new to CFD, TAU and related tools you need to get used to a lot of different software products and work methods. The best way to do this is to read the manual(s).

- TAU Beginners Guide

  The present TAU beginner’s guide gives an introduction to the basic usage of the TAU code. It is not a stand alone document, but has to be used in combination with other documentation for the DLR TAU code available.

- TAU Basics

  This user-guide is aimed at describing the basic installation procedure for the DLR TAUCode, and to provide a short introduction to the handling of the code by way of some simple examples.

- TAU Users Guide

  Complete description of all parameters for DLR TAU code.

- Technical Documentation of the DLR TAU-Code

  The DLR TAU-Code is a development of the DLR-Institute of Aerodynamic and Flow Technology at Göttingen and Braunschweig. This document gives an overview about technical aspects.

- Compiling TAU with PETSc (Jan 2009)

  TAU uses the PETSc sparse linear solver library for some modes of the linearized solvers (adjoint, frequency domain, error estimation, etc.). Some functionality of these solvers is only available with PETSc. This document describes first PETSc compilation 1)-5), and then modifications to the TAU compilation process required when linking with PETSc.

- TAU-Python Interface Guide

  This section of the guide contains descriptions of the functions of the TAU-Code which may be called from a user-created Python script. As far as possible, the data that is required to be in memory for the function-call to work will be listed. Please note that this guide is a work in progress, as well as being TAU-Release dependent.

- TAU Transition module (V9.28)

  Predicting and modelling the laminar-turbulent transition in Reynolds-averaged Navier-Stokes (RANS) solvers can be an important requirement for the computation of flows around general two- and threedimensional geometries. Neglecting or using inaccurate transition locations can lead to significant errors of the predicted aerodynamic performance.
