Construction of the Voronoi diagram with constraints on a plane

Purpose. The problem of construction the Voronoi diagram with constrains on a plane, also known as the generalized inverse Voronoi problem, is considered. The problem is to construct a Voronoi diagram on the plane, which edges lie on a given set of segments.

Methodology. Constructing a Voronoi diagram with constraints is based on the formation of a set of circles and the placement of sites of the diagram at the intersections of these circles. The procedure for constructing a diagram is described by a formal language to prove its correctness.

Findings. An algorithm for constructing a constrained Voronoi diagram with proof of correctness is proposed. A procedure for constructing a two-dimensional computational grid based on such a diagram is described.

Value. The proposed algorithm is rather brief and has a simple proof of correctness. The use of such a grid can improve the accuracy of the numerical solution of some problems in fluid mechanics.
