Others
The tabs cover the settings numgeo-GiD knows about. This tab is for anything they do not.
Additional keywords
Text entered in the upper area is added verbatim to the material, after everything defined in the other tabs. Nothing is checked or corrected, so it must be valid numgeo syntax — see the material reference for the available keywords.
Notes
The Notes area at the bottom is for your own comments. It stays with the material and is never used in the calculation.
