Geometry
Geometry Formation
FLOOXS forms geometries using the level set method. This method allows FLOOXS to solve the moving boundary problem on a special finite element grid called an anisotropic mesh (anisomesh). A geometry is available for processing anytime a solution is available on the anisomesh. Geometries fit broadly in two categories: deposition and etch. A deposition creates a new material on top of an existing mesh (upward boundary propagation). An etch cuts into a material stack (downward boundary propagation).
Mesh Generation
Three meshing engines are available in FLOOXS:
- GMSH - most reliable for deposition and etch
- Triangle - reliable for deposition but lower quality meshes
- Internal (etch only) - very reliable for etch but splits existing elements in the grid.
