Getting Started
Overview
Welcome to the FINE™/Turbo User’s Guide, a presentation of NUMECA’s Flow INtegrated Environment for computations on structured meshes. This chapter presents the basic concepts of FINE™/Turbo and shows how to get started with the program by describing:
what FINE™/Turbo does and how it operates,
•
how to use this guide,
•
how to start the FINE™/turbo interface.

Introduction
1-2.1
Components
The resolution of Computational Fluid Dynamics (CFD) problems involves three main steps: •
spatial discretization of the flow domain,
•
flow computation,
•
visualization of the results.
To perform these steps NUMECA has developed three software systems. The first one, IGG™, is an Interactive Geometry modeller and Grid generation system for multiblock structured grids. The second software system, the FINE™/turbo solver, is a state of the art 3D multiblock flow solver able to simulate Euler or Navier-Stokes (laminar or turbulent) flows. The third one, CFView™, is a highly interactive Computational Field Visualization system. These three software systems have been integrated in a unique and user friendly Graphical User Interface (GUI), called FINE™, allowing the achievement of complete simulations of 3D internal and external flows from the grid generation to the visualization, without any file manipulation, through the concept of project. Moreover, multi-tasking capabilities are incorporated, allowing the simultaneous treatment of multiple projects.
