NETGEN is an automatic 3d tetrahedral mesh generator.

Accessible and cross-platform C++-based application that enables you to quickly develop and generate 3D meshes in no time at all

NETGEN is a powerful and automatic 3D tetrahedral mesh generator. The application is designed to accept input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format.

This program will generate triangular or quadrilateral meshes in 2D, and tetrahedral meshes in 3D.

The input for 2D is described by spline curves, and the input for 3D problems can be defined by Constructive Solid Geometry (CSG), the standard STL file format, or via Boundary Representations (BRep/IGES/STEP) when compiled with OpenCascade support.

NETGEN also provides modules for automated mesh optimization and hierarchical mesh refinement. Curved elements or arbitrary order are supported.

Features.

    Two and three dimensional surface meshing
    Three dimensional volume meshing
    Delaunay and advancing front mesh generation algorithms
    Constructive solid geometry, or boundary representation
    Mesh refinement algorithms
    High order curved elements
