This article describes the methodology of generating block-structured computational grids for turbomachine blade passages implemented in the TurboR software. The basis of grid generation process is the variational method. The combination of the energy density functional and cell size functional is used. In order to speed up the process of grid generation a multigrid approach is applied. An algorithm for constructing a block topology in the blade passages is proposed, which takes several spanwise sections of the blade into account simultaneously. To create a block topology of axisymmetric effects a medial axis based method is used. Main features of the software are discussed, the presented results demonstrate high quality of the grids generated in a fully automatic mode.
