Abstract

This chapter presents the geometrically exact beam theory implemented by the Legendre-spectral-finite-element (LSFE) method. An LSFE is a high-order finite element with nodes located at the Gauss-Legendre-Lobatto points. These elements can be an order of magnitude more computationally efficient than low-order finite elements for a given accuracy level. The new module, BeamDyn, is incorporated in the FAST modularization framework for dynamic simulation of highly flexible composite-material wind turbine blades. The framework allows for fully interactive simulations of turbine blades in operating conditions. A numerical example using the NREL 5-MW wind turbine is provided to validate BeamDyn and examine the LSFE performance as well as the coupling algorithm in the FAST modularization framework.
