%description
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.
