Millipede is a structural analysis and optimization component for grasshopper. It allows for very fast linear elastic analysis of frame and shell elements in 3d, 2d plate elements for in plane forces, and 3d volumetric elements. All systems can be optimized using built in topology optimization methods and have their results extracted and visualized in a variety of ways.

In addition millipede implements a few basic geometric features [extraction of iso surface meshes from volumetric scalar fields or and extraction of curved contours over any mesh] and a few numerical analysis tools [Fast fourier transforms in 1 and 2 dimensions, sparse linear system solver and eigenvalue calculation for large matrices using functionality from the intel math kernel library]

The new version of millipede includes the surface reparameterization module that enables the generation of vector field aligned patterns over any mesh. This functionality is particularly useful for the creation of principal stress aligned grid shells and reinforcement patterns.
