摘要：The method involves creating a database of three-dimensional numericalmodels of a valve sector (100) and lateral valve sectors (200, 300), by digitizing. A criterionto select an arrangement of the sectors is set, and a desired value for the criterion is set.

Relative positions of the sectors are determined, for various evaluated arrangements,when the sectors are assembled together. A value of the criterion for the arrangementunder evaluation, is determined according to the positions. The arrangement, in which thecriterion has the value closest to the desired value, is retained. The criterion is a functionof the shapes and the relative positions of the sectors.
