OpenFOAM or Fluent, which one is better in the categories below?
1- Ship hydrodynamics and sea keeping 2- Thermal analysis and heat transfer problems |

By "better" I mean accuracy of the solution when the simulation results are compared with the corresponding experimental data.

Hi,
you can find presentation like http://sourceforge.net/projects/open...s.pdf/download Taming OpenFOAM for Ship Hydrodynamics Applications by Sung-Eun Kim OF is capable if you are an cfd-expert, consulting companies like "engys, icon,..." try to give a helping hand by best practice start settings in their GUI based preprocessing tools. S.th that Fluent also does. |

the accuracy is more user dependent than software dependant.
unless there are major errors or quirks (and there aren't, afaik), both softwares will provide accurate results if the case is set up well and the mesh is good enough |

I am also using OpenFOAM for some seakeeping simulations and the accuracy I get from the software is very good. But, I also want to do some thermal simulations and I have heard that OpenFOAM is not very good at that. And I was just wondering if I should use Fluent for thermal and OpenFOAM for seakeeping or OpenFOAM for both.
Thank you very much for your answers, |

from my experience, Fluent is much easier for heat transfer ! I love openfoam but it is a pain when we talk about heat

Hai friends,
I am trying to do 2d naca 0012 Airfoil analysis in openfoam.For that I did meshing in gambit. My mesh file name is :naca 0012.msh Then i am trying to convert fluent mesh to openfoam mesh. For that I got error in terminal window like mrk@ubuntu:~/OF/openfoam220/tutorials/incompressible/simpleFoam/vk/airFoil2D$ fluentMeshToFoam naca 0012.msh fluentMeshToFoam: command not found Plase let me know polymesh ie folder inside constant & Please help me how to convert mesh |

make sure there is no space between NACA0012
