We provide software for computing the Morse-Smale complex of a scalar field defined on a triangle mesh and 3D structured grid. The Morse-Smale complex is a topological data structure that partitions datasets based on the gradients of an input scalar function. It has been used for visualization and analysis of scalar data from a wide range of disciplines including combustion analysis, cosmology, structural biology, climate studies, and medical imaging. The software implements algorithms described in two papers [1, 2].
