Abstract
This contribution deals with further development of Boundary Domain Integral
algorithm for computation of laminar viscous fluid flows governed by the Navier-
Stokes equations. The algorithm uses the velocity-vorticity formulation and is
based on vector-potential formulation of flow kinematics. This results in an accurate
determination of the boundary vorticity values, a crucial step in constructing
an accurate numerical algorithm for the computation of flows in complex geometries,
i.e. geometries with sharp corners. In order to lower computational costs
the domain velocity computations are done by the segmentation technique using
large subdomains. After the kinematics equation is resolved, the vorticity transport
equation is solved using a macro
