Computational fluid dynamics (CFD) has been utilized to investigate straight and side flow over a simplified model of the concept high-speed Next Generation Train of the DLR. Large eddy simulation (LES) with a finite volume method for unstructured grids and a lattice Boltzmann method (LBM) were performed to compare the results. The Reynolds number of the flow was Re=2:1x10^5 and the investigated yaw angle was 30°. The flow fields and the aerodynamic forces predicted with these two different methods are compared for the validation case of the flow past a sphere and the flow around the generic train model. Both approaches yield similar force predictions and exhibit different strengths and weaknesses throughout the computational process which are discussed.
