Abstract
Modern approaches to visualization and automatic identification of regions are discussed separation of three-dimensional boundary layers. The corresponding algorithms are implemented within the framework of the original LOTRAN software package, designed to calculate the position of the laminar-turbulent transition in boundary layers over surfaces of small curvature. Their work is demonstrated using two configurations: a swept wing and a prolate spheroid.
