New Version of OpenFlower Open Source CFD Software Released
Posted Tue May 31, 2005 @03:43PM
Print version Email story Tweet story
Open Source OpenFlower (FLOW solvER) is a C++ open source Linux CFD code mainly intended to solve the turbulent incompressible Navier-Stokes equations with a LES approach. It can deal with arbitrary complex 3D geometries with its finite volume approach and multi-element grids. One of its main objectives is to give to the CFD community a plug'n play CFD software, easy to use and install (no complicated compilations needed since it is written in standard C++ and also comes along with binary version of the code for Linux).

It includes in particular the following new features since the last version:
  • A second order convection operator;
  • A flexible structure called "Algorithm" which enables one to "easily" build new resolution algorithms and coupling between equations;
  • An interface with the LASPack linear algebra library for solving linear systems, in particular the Poisson equation for pressure;
  • A Navier-Stokes algorithm based on a finite-volume and pressure-velocity coupling formulation used at Stanford CTR along with a 2nd order Adams-Bashforth time scheme;

The code is fully Open Source, and available on the SourceForge website. Users can either download the source package (containing several input example files) or a binary executable compiled for Linux distributions. It is mainly interfaced with Gmsh open source meshers for CAD, meshing and post-processing.
