Hi I just compiled from the latest source code release. It doesn't abort, but it only generates the triangulation of the volume surface.
Changing from: 8 corners of the box 1e-5 apart with a 5-e7 characteristic length to: 8 corners of the box 1 apart with a 0.05 characteristic length causes meshing to succeed. The messages in the log, are much more numerous and are all similar to: Info : 5414 open elements Error : ERROR: Edge 2 - 28 multiple times in surface mesh Error : ERROR: Edge 2 - 30 multiple times in surface mesh Error : ERROR: Edge 14 - 28 multiple times in surface mesh Error : ERROR: Edge 8 - 46 multiple times in surface mesh Error : ERROR: Edge 30 - 31 multiple times in surface mesh Error : ERROR: Edge 31 - 32 multiple times in surface mesh Error : ERROR: Edge 32 - 33 multiple times in surface mesh Error : ERROR: Edge 33 - 34 multiple times in surface mesh Error : ERROR: Edge 34 - 35 multiple times in surface mesh Error : ERROR: Edge 35 - 36 multiple times in surface mesh Error : ERROR: Edge 36 - 37 multiple times in surface mesh Regards, Juan On Thu, Oct 2, 2008 at 1:55 PM, Antoine Dechaume <[EMAIL PROTECTED]> wrote: > Hi Juan, > > your version of gmsh is quite old, you should give a try to a recent one. > > Antoine. > > > On 2-Oct-08, at 12:52 PM, John Doe wrote: > >> I ended up drawing the volume in the gui and it still crash, but now >> for a different reason. >> >> If I have the 8 corners of the box 1e-5 apart with a 5-e7 >> characteristic length the mesher crashes. >> >> If I have the 8 corners of the box 1 apart with a 0.05 characteristic >> length the mesher works. >> >> This is gmsh 2.0.8 packaged for Ubuntu for a amd64 machine. >> >> Is there a way to make this work without crashing? >> >> Regards, >> >> Juan >> >> On Thu, Oct 2, 2008 at 12:56 PM, John Doe <[EMAIL PROTECTED]> wrote: >>> >>> I am learning to use gmsh, and I'd like to create a volume from the 6 >>> surfaces of a box. >>> >>> Right now gmsh is aborting, and I think that it may be because I don't >>> understand how to order the indices in the surface loop command.
