IGUANA Mesh is an open source three-dimensional finite element meshing plugin for Grasshopper. It uses Gmsh as mesh generator and stores all topological data within a half-facet data-structure in order to provide a comprehensive topological description of discrete models even for non-manifold meshes and mixed-dimensionalities. The plugin runs on x64 architectures and was tested with Rhino 6 64-bit.
