Fenix

ADDON. Version . Released on 01-Jan-0001. Provides 172 components. Created by protoGen Software. Features 0 video tutorials.

Fenix is a full-featured elastic finite element analysis and structural design plug-in for Grasshopper. It is both fast and powerful. Use it for anything from a single beam to a high-rise building, and everything in between! It is capable of handling large building models that mesh into tens or hundreds-of-thousands of elements. Fenix includes a multitude of element types, including frames, links, springs, shells, and solids. Multiple formulations are available for many elements, allowing more control over accuracy and speed.
