enGrid - open-source mesh generation
ENGRID is an open-source mesh generation software with CFD applications in mind. ENGRID uses the NETGEN library for tetrahedral grid generation and an in-house development for prismatic boundary layer grids. Internally, ENGRID uses the VTK data structures as well as the *.vtu file format. It provides native OPENFOAM support (OPENFOAM is a registered trade mark of OpenCFD Limited), including export capabilities for complete OPENFOAM cases (including boundary conditions and solver setup).
ENGRID is released under the GPL and we hope that it is a useful addition to the open-source CFD community. So far the implemented algorithm proved to be quite robust and it does not require much user interaction.
