[ GiDlist ] Numbering Scheme for Structured Brick Elements

[Mark D Moeckel]

Good Day,

I am evaluating GID as a pre and post processing package for use with
computational fluid dynamics.

The problem types that I expect to grid and analyze will require multi-blocks
or several volumes in GID terminology.

I can not determine how GID numbers the elements. For example, I would like to
always create structured brick elements that are number first along the x axis
and then the y axis for various z axis values.

I have been trying to determine what determines the order in GID, is it the
ordering of the surfaces making up the volume, the order of the lines making
up the surfaces, both, or none of the above.

I would very much appreciate some insight into the GID structured brick mesh
numbering (and generating) scheme.

Thank you very much.
