Dear all,
I'm trying to import on OpenFOAM a 3D Mesh I created using gmsh-2.5.0. I tried to figure out the right procedure reading several posts on this forum, and this is what I have done:
When I try to run "paraFoam" it crashes! Thanks in advance |

Hello Francesco,
I think the problem comes from "Max aspect ratio: 3062.79", so in some regions the size of the cells is 3000 times bigger in one direction than in another. Try meshing a simpler geometry first and keep max. aspect ratio below 10-100. Zoltan |

Hi Zoltan,
thanks for your reply! You were right.... I tried with a simpler geometry and it worked, I got checkMesh ok! But when I try to visualize the 3D mesh on paraView it still crashes. I also tried increasing "cl" in my .geo file to have a small number of cells. I got a 3D mesh with only 48 cells, but parView it still unable to open it. What could be the reason? Do you think could be related to my hardware? Maybe my pc has not enough memory for graphical applications... Francesco |

Hi Zoltan,
using the function "Optimize(3D Netgen)" in gmsh-2.5.0, I was able to get the mesh I wish avoiding "High ratio aspect" error in checkMesh. But I'm not yet able to visualize it on paraView. When I ran paraView, on the left column where is "Mesh parts" I have the physical surfaces I defined in my mesh using gmsh, when I select them and click apply nothing happens... Better, my screen become grey and my pc seems to work, but the 3D Mesh doesn't appear on the screen. Someone experienced problem to visualize 3D mesh in paraView? Do you think could be an hardware related problem? Francesco |

Dear Francesco,
Try a coarser mesh and check if you ran out of memory. Zoltan |

Hi Francesco,
I know it is late and you may have already solved your problem. If you have not here could be the the solution to view the mesh in paraview the patches which you selected in gmsh have to be defined first. You can still view the mesh by deselecting the volume fields in the properties pannel in paraview. Hope this helps Regards Abhinay |

Hi everybody,
I am new to gmsh. When I tried to convert the mesh file to openfoam, am getting this error. Skipping tag $ParametricNodes at line 93 Starting to read cells at line 835074 Cells to be read:793944 --> FOAM FATAL ERROR: 20 not found in table. Valid entries: 0() From function HashTable<T, Key, Hash>:perator[](const Key&) const in file /home/bluesim/OpenFOAM/OpenFOAM-1.6.x/src/OpenFOAM/lnInclude/HashTableI.H at line 128. FOAM exiting Can someone help on this? |

Hi,
According to Gmsh documentation, element ID 1 has 2-node line elements (http://www.geuz.org/gmsh/doc/texinfo...II-file-format). Are you sure your mesh is 3D? |

hello guys,
I am not able to convert 3D mesh file from gmsh to openfoam. If I do that, it says may be your mesh has 3D elements and may be you have not exported the 3D elements. please I need help Cheers |

Can you put a picture on what are you trying to mesh in 3D gmsh?
Best, |

Try this;
Code:
l = 6; r = 2; Point(1) = {0, 0, 0, 0.0}; Point(2) = {l, 0.0, 0, 0.0}; Point(3) = {0, r, 0, 0.0}; Point(4) = {l, r, 0, 0.0}; Line(1) = {3, 1}; Line(2) = {1, 2}; Line(3) = {2, 4}; Line(4) = {4, 3}; Line Loop(5) = {4, 1, 2, 3}; Plane Surface(6) = {5}; Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{6}; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{23}; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{40}; } Extrude {{1, 0, 0}, {0, 0, 0}, Pi/2} { Surface{57}; } Surface Loop(74) = {6, 23, 15, 18, 22}; Volume(75) = {74}; Surface Loop(76) = {23, 40, 32, 35, 39}; Volume(77) = {76}; Surface Loop(78) = {6, 66, 69, 73, 57}; Volume(79) = {78}; Surface Loop(80) = {40, 57, 49, 52, 56}; Volume(81) = {80}; d1 = 1; d2 = 1; d3 = 1; N1 = 30; N2 = 30; N3 = 18; Transfinite Line {2, 4, 42, 25, 8} = N1 Using Progression d1; Transfinite Line {1, 43, 26, 9, 3, 45, 28, 11} = N2 Using Progression d2; Transfinite Line {65, 14, 31, 48, 13, 64, 47, 30} = N3 Using Progression d3; Transfinite Surface "*"; Transfinite Volume "*"; Recombine Surface "*"; |

i have same problem. my gmsh script.
//+ Point(1) = {-0, -0, 0, 1.0}; //+ Point(2) = {0.2, -0, 0, 1.0}; //+ Point(3) = {0.2, -0.4, 0, 1.0}; //+ Point(4) = {0, -0.4, 0, 1.0}; //+ //+ Line(1) = {1, 2}; //+ Line(2) = {2, 3}; //+ Line(3) = {3, 4}; //+ Line(4) = {4, 1}; //+ Line Loop(1) = {4, 1, 2, 3}; //+ //+ Plane Surface(1) = {1}; //+ Physical Line("inlet") = {1}; //+ Physical Line("outlet") = {3}; //+ Physical Line("chill boundary") = {2}; //+ Physical Line("symmetryPlane") = {4}; //+ Extrude {0, 0, -0.02} { Surface{1}; Layers{1}; Recombine; } //+ Transfinite Surface {1}; //+ Transfinite Surface {26}; //+ Transfinite Surface {21}; //+ Transfinite Surface {25}; //+ Transfinite Surface {13}; //+ Transfinite Surface {26}; //+ Transfinite Surface {17}; //+ Transfinite Line {4, 2, 6} = 136 Using Progression 1; //+ Transfinite Line {6, 8} = 136 Using Progression 1; //+ Transfinite Line {1, 3} = 252 Using Progression 1; //+ Transfinite Line {7, 9} = 252 Using Progression 1; //+ Recombine Surface {1, 13, 26, 17, 21, 25}; please anybody tell me..what we do for this |
