Dear Shim,

please always reply to the list...

If you could upload the file somewhere and send a link, would be perfect. Sending large files over the list is not the preferred way.

Thank you Christian,


>> If you construct/read a mesh, you can assign a boundary parametrization (the boundary segment) to each foundary face of the mesh. In your case UG reports, that you have roughly 8 times as many boundary segments as you have faces. This sound pretty much as if your mesh is already invalid.

- Does your sentence mean that I should generate a new mesh model for UG computing?

The mesh file is generated by tetgen program, and I used this file without modify as an input file for computing.

Of course I'm able to provide mesh file to you.  Would I send the mesh file as attachment via email? Or is there other way to send the mesh file to you?


Thanks again for your help.


Best,

If you construct/read a mesh, you can assign a boundary
parametrization (the boundary segment) to each foundary face of the
mesh. In your case UG reports, that you have roughly 8 times as many
boundary segments as you have faces. This sound pretty much as if your
mesh is already invalid.

- Are you reading a gmsh file? Or how are you constructing the mesh?
- Can you provide the mesh file (or a minimal example)?

> Is there a limitation for the number of boundary segments?

If I remember UGGrid correctly, there is a limitation, but this is not
your problem here and I doubt that you will hit this limit.

> Should I reduce the number of segments?

Does this mean that you manually specify the segments?
