This code comprises of a tool called Felix, for exploring filamentary structures in cosmological simulations. Initially, this code was developed to compute the Morse-Smale complex of 3D tetrahedral meshes. It now includes code to compute the MS complex of 3D structured grids.
The following paper describes the algorithms implemented in Felix. Please do cite it if you use the software for your work.
