 Introduction

A highly interactive Geometry Modeller and Grid Generation system, based on the most advanced software tools and standards. IGG provides all necessary interactive tools to create rapidly complex 2D/3D structured multiblock meshes. It is interfaced with CAD-CAM systems through an IGES translator, enabling fast loading of external geometry.
