Emu is an interactive structural analysis and form-finding tool based on a 6DOF (6 degrees of freedom) formulation of the dynamic relaxation method allowing engineers and designers to run bi-axial bending and torsion simulations. It is aimed to be used in early design stages but yet giving real structural feedback.

Emu was developed as part of a Master's thesis in Structural Engineering and Building Technology at Chalmers University of Technology, with the aim of simulating the very non-linear process of elastic gridshell erection.
