A method of determining the boundary conditions for the 
Navier-Stokes equations in stream function-vorticity variables, 
used for simulation of a nonstationary, asymmetric laminar flow of 
an incompressible viscous fluid around bodies, has been proposed. 
Universal relations for desired functions on surfaces around which 
the stream flows, independent of the method of spatial discretization, 
have been obtained.
