The characteristics of the oscillations of a cylindrical 
pendulum in a square cavity filled with an incompressible viscous 
fluid have been forecast on the basis of the joint numerical modeling 
of two-dimensional unsteady laminar flow around a circular cylinder 
with the use of movable sliding grids and solution of dynamic equations.
