Abstract A grid generation method is proposed for an arbitrary two‐dimensional domain. The method, based on the Delaunay triangulation, is modified so that it can be used as a grid generator for an arbitrary two‐dimensional area with complex boundary geometry. Input data for the method are the co‐ordinates of all nodes and the ordering of nodes on each boundary. Its efficiency is examined through a number of actual problems, and a numerical experiment clarifies that the grid generation requires a CPU time which is proportional to the number of nodes.
