Information

Millipede

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.

Radial load in Millipede Topostruct2D & Topostruct3D

Hello everyone !,Is there a possibility or a way to set loads as "radial" in Millipede ? The "radial" option is available in the Sawapan Topostruct software, at least for the 2D system (see screenshot). Actually, I would like to apply torque loads…Continue

Stress based Structure Optimization for multiple loadcases 7 Replies

Hi All and Panagiotis,I have again a question : Let's assume I have an Object I would like to find an optimized structure for. I would start applying a single direction load and would get stresslines which I then would use to for example…Continue

Target Density

I am trying to run some 2D topology optimisation and I am having some doubts about the target density. My input is a slider that varies from 0 to 1, however, changing the value of the slider does not really affect the end result. How can I define…Continue
