[GiDlist] surface mesh import

[My VDI Freemail]

Hello GiD,

I generated a simple quadrilateral mesh in GiD, which I saved as GiD mesh.
Then I wanted to import this as surface mesh (according to the reference manual this should work with GiD mesh as well as STL file). But I got only the error message "VoidPlex::set_at. Invalid void index 0" and then GiD exited with a core dump.
What's the reason for it?
The simple GiD mesh looks like the following:
===========================================
MESH dimension 3 ElemType Quadrilateral Nnode 4
Coordinates
1 100 0 0
2 100 100 0
3 100 50 0
4 50 0 0
5 0 0 0
6 50 100 0
7 50 50 0
8 0 50 0
9 0 100 0
end coordinates

Elements
1 8 7 6 9
2 5 4 7 8
3 7 3 2 6
4 4 1 3 7
end elements
==========================================

Thanks for your support.
Best regards,
Ruediger

This is a bug of GiD 7. It is corrected for the next beta version. Until
this correction, instead to create
a surfmesh from quadrilateral meshes, use only triangular GiD ascii or STL
meshes.

Thanks for your bug report.

Many thanks for your response Enrique,

Actually the import of triangular surface meshes works quite well. But unfortunately the surfaces created in GiD are not NURBS type. This means, that all subsequent actions (such as trimming etc.) are not valid, because of the type of the surface. Additionally the conversion to NURBS often does not work because the surfaces are not planar or coon surfaces.
How could I work with the surfaces generated?
