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