Karamba3D is an interactive, parametric engineering tool that allows you to perform quick and accurate Finite Element Analysis (FEA). It has been specially tailored to the needs of design professionals in the early design phases. Karamba3D is embedded in the parametric environment of Grasshopper in the 3d modelling program Rhino3D. This makes it easy to combine parameterized geometric models, Finite Element calculations and optimization algorithms like Galapagos, Octopus, Wallacei and many more. Karamba3D can also be used as a standalone .NET library for integrating Finite Element functionality into your scripts.
