The urgency of constructing spatial curvilinear grids in areas with complex geometry is formulated. An overview of the construction of two-dimensional curvilinear computational grids is given. The article describes the rationale for the fact that the methods described in the review cannot fully calculate the flow parameters in regions with complex geometry. A method for constructing three-dimensional grids for bodies with arbitrary surface geometry is described. The results of constructing a three-dimensional grid are presented using a hemisphere as an example. An estimate of the measures of non-orthogonality for the test case is given.
