I modified the end of my code this way:
Code:
mesh.movePoints(points); runTime.functionObjects().off(); runTime++; mesh.write(); |

I tried to understand a little how all this work.
In an fvMesh, the write() method is a reimplementation of the virtual write() inherited from polyMesh, itself inherited from objectRegistry (and itself from regIOobject). But, when fvMesh::write() is called, the following code is executed Code:
bool fvMesh::write() const { return polyMesh::write(); } The problem in my case is that the only written file is points. When the fvMesh mesh is created, with Code:
Foam::fvMesh mesh ( Foam::IOobject ( Foam::fvMesh::defaultRegion, runTime.timeName(), runTime, Foam::IOobject::MUST_READ ) ); Plus, if I try a Code:
mesh.names() Code:
11 ( cellZones fvSolution meshPhi points neighbour faces faceZones fvSchemes pointZones boundary owner ) Last edited by johndeas; July 16, 2009 at 06:10. |

John,
it's all about saving disk space. When OF write a mesh, it only saves data that has changed after the last dump. On read OF goes backwards through the time dumps and collects the necessary data. All what you have to do in order to obtain a "normal" mesh is to copy 1/polyMesh/points into constant/polyMesh and delete the "1" time directory. Henrik |

Thank you for the information !
Well rewriting the whole polyMesh forced me to dive a little into OF structure which wasn't a bad thing, after all |

Something that might be attractive (my 2 cents...) would be to have the same kind of rule for field reading. If I apply a preprocess on the mesh, which outputs to other time directories, the process of field reading would detect and use the latest version so I don't have to manually copy everything on the last time directory.

Hi
I am also performing LES on channel flow and i would like to use ane hyperbolic mesh does someone has some know how to do that how to implement the routine in the code |

Hello Alberto,
I am very new to OF and would like to know if it is possible for you to send me your code about "hyperbolic" (or any other analytical function" meshing? Because I would like to implement it on a variable cross-sectional cylinder, with the number of cells depending on the radius, for instance... Thank you very much! Best, Bertrand |
