Numerical Grid Generation Wiktionary-Structured Knowledge for Research and Education (Data Base NGGW- Permanent Product of European Project EUA4X European Atelier for Engineering and Computational Sciences)

In this paper we present the advanced version of the Numerical Grid Generation Wiktionary (NGGW), the online dictionary on the MediaWiki collaborative platform. NGGW is an open access free tool for research and education in numerical grid generation. We illustrate and discuss the basic criteria to design this encyclopedic dictionary, we describe its scientific contents and we show a few representative pages. We present the sets of categories used to structure the grid generation knowledge.
