A multigrid strategy for the solution of the Euler equations in three-dimensional domains is presented. The procedures include data structures and mesh modification tools for defining unstructured adaptive multilevel meshes on general curved domains and an implicit time-marching multigrid finite element solver. The code is equipped with special features for the solution of problems relevant to rotorcraft technology. The approach is applied to the simulation of hovering rotors, and the numerical results are compared with experimental data and with numerical simulations obtained using a mesh adaptive single-grid generalized minimal residual (GMRES) solver.
