Dear all, First, greetings of the new year 2013 . I want to know how you guys generate complex FE mesh for libmesh. Is there any good open-source software on mesh generation for libmesh? Looking forward to the recommendations. Thanks. Walter |

Not open source, but for really complex stuff we use Cubit: http://cubit.sandia.gov/ Sent from my iPad On Jan 2, 2013, at 9:38 PM, walter kou <wal...@gm...> wrote: Dear all, First, greetings of the new year 2013 .

Hi Derek, Thanks for your reply. The FE mesh in my current application, though it is 3D, will not be "really complex" as shown in the website of Cubit. While I find Gmsh from Libemsh-wiki website looks good. Could Gmsh prepare FE mesh for libmesh? If so, what kind of files will Gmsh generate for libmesh?

Could Gmsh prepare FE mesh > for libmesh? If so, what kind of files will Gmsh generate for libmesh? Yes, libmesh can read gmsh meshes. Gmsh typically generates tetrahedral meshes, but I believe it can also do extrusions of 2D meshes into wedge elements. For more information, you might want to check out the examples on their site, http://geuz.org/gmsh/ -- John |

Hi all, But when I try to run gmsh: ./gmsh, I get error on missing libraries. And after using command: ldd gmsh, I find missing libraries: libgmp.so.3 => not found libgfortran.so.3 => not found My computer: fedora 17 x86_64; and actually if I type: locate libgfortran.so.3, I find I have libgfortran.so.3: /usr/lib64/libgfortran.so.3 Strange, do you guys encounter similar problem?
