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:

1. GMSH - most reliable for deposition and etch
2. Triangle - reliable for deposition but lower quality meshes
3. Internal (etch only) - very reliable for etch but splits existing elements in the grid.
