Numeca's Interactive Geometry Modeler and Multi-Block Structured Grid Generator


IGG™ enables the creation of 2D and 3D arbitrary shapes and multi-block structured grids on 2D/3D geometries. IGG™ supports python scripts for automatic meshing reply into optimization loops.

Model geometries, create and script block-structured grids, in a powerful GUI
