This paper presents a study of a wind turbine subjected to wind and seismic loading, carried out using COMSOL Multiphysics. The dynamic properties and response of wind turbine structures are of interest, as recent developments in wind energy have led to the design and construction of increasingly large and flexible turbine structures. A typical turbine structure model was created in ...

A 2D multiphysics model has been developed to simulate heterojunctions separating abruptly doped semiconductor layers of different dopant concentrations. Numerical results are presented for the case of nN, pN and PpN heterojunctions, and a general procedure for simulating multiple heterojunctions is described.
