      We discuss a procedure for calculating curvilinear grids in simple and complex spatial regions. This is based on interpolating coordinate values of 3-D region inner points over boundary surface nodes. Grid line smoothness and orthogonality and equal volumes in nearby cells are achieved by moving inner nodes depending on quality parameter values. 2- and 3-D regions of various complexity are calculated.
