Welcome to FramAT’s documentation!

FramAT (Frame Analysis Tool) is a FEM implementation of the Euler-Bernoulli beam theory (also known as classical or engineering beam theory). The tool was initially written for a low-fidelity aeroelasticity model, but FramAT is a general purpose FE beam implementation. Most notably, FramAT provides the following functionality.

• Euler-Bernoulli beam analyses in 3D

• Assembly of complex beam structures

• Simple to use and documented Python API

• Highly automatable model generation

• Elaborate definition of beam geometry, properties and loads

• Highly customisable plots

• Elaborate result objects post-processing
