matVLM: Versatile UVLM in Matlab

matVLM is an open-source Matlab library that implements the unsteady vortex lattice method (UVLM), specially tailored for the analysis of multi-wing flapping systems. While its primary focus is on flapping systems, matVLM’s flexibility allows for a broad spectrum of applications. This includes dynamics such as flapping, pitching, plunging, or any combination thereof across multiple wings. It is also capable of modeling rotating wings and, as expected, can also analyze steady wings.

The library offers a variety of models for calculating aerodynamic loads, enabling users to assess outputs and computational efficiency effectively.

A pivotal element of my PhD thesis, matVLM underpins the validation of experimental findings from the MechaRaptor setup focused on tandem flapping wings. It also plays a crucial role in the validation of Rotare (BEMT) for coaxial rotors in axial flow, highlighting its critical contribution to advancing our understanding of complex aerodynamic phenomena.
