Dear Forum,
I am trying to mesh a box with a spherical cavity to model the flow around a sphere in OpenFOAM. I can easily produce my mesh in ANSYS and export it in .iges format. When I import the .iges in gmsh I only get outline. I understand gmsh is not set up to read CAD models. So I can use the outline of my domain and remesh in gmsh. My question is: is this procedure still valid? http://openfoamwiki.net/index.php/Howto_importing_fluent_mesh_with_internal_wall s Does anybody know of an easier way to produce a mesh for a box with a spherical cavity on the inside? Thank you again, Alessandro |

Dear Forum,
I also wanted to ask if it is possible to produce an OpenFoam mesh given a text file with node locations and their connectivity. As far as the previous message, has anybody worked on such problem? Could you suggest any easy way to create a patch for the inside cavity (a sphere in my case)? Thank you for you help, Alessandro |

If your points are the points of a block structured mesh have a look at the plot3DToFoam sources ($FOAM_UTILITIES/mesh/conversion). The plot3D format is (usually) a single block structured mesh and gives only the coordinates in some i,j,k format.

Hello Alessandro Spadoni,
> Does anybody know of an easier way to produce a mesh for a box with a spherical cavity on the inside? Maybe the fifth tutorial "t5.geo" http://www.geuz.org/gmsh/doc/texinfo/gmsh_8.html#SEC51 in the gmsh reference manual http://www.geuz.org/gmsh/doc/texinfo/gmsh.html can help you? It does not seem to be a big problem with gmsh. Regards, Gero. |
