[ GiDlist ] preprocessor bug
Posted: Thu Oct 26, 2000 7:36 pm
Please, send us a sample attached that it shows the problem.
Includes the gid files and the problem type files enclosing a brief explanation of where it fails.
if it prefers it can send it to my private direction.

Dear GID users and developers
During my little experience working with GID and using it in solving several 2D and 3D problems, I noticed that there are problems with the preprocessor writing the element connectivity for a complex geometry in a consistent manner.
As far as I understand, The element connectivity order can be controlled by using the following statement in the .bas file
*elemsConec(1)*elemsConec(2)*elemsConec(3)*elemsConec(4)... etc
The following have been observed:
using the same .bas file for two different 3D meshes, the first one is a simple geometry consists of one single volume and the second is a complex geometry
consists of several volumes. It was observed that the same .bas file works well for the simple geometry and writes the exact element order as in the .bas file.
However, it produces inconsistent order of element connectivity for the more complex geometry, where, part of the mesh is being written in a correct manner and the rest of the elements are not.
This problem has been repeated several times for different problem configurations and I had to write the elements connectivity by hand !
Hope this is not a bug in the program.
If you have explanation or suggestion for this problem please email me.
Regards
