In this paper the modeling of the oscillatory motion of a circular cylinder in a viscous incompressible fluid in the package OpenFOAM is considered. Much attention is paid to the construction of the numerical model in the package: to discretization of the solution area, to the choice of the numerical scheme and algorithms of solution, to assessing the accuracy of the methods. The results of the calculations at the low Stokes numbers are presented: a map of regimes is constructed, a visualization of typical flows was done, a comparison of the data with the results of laboratory experiments was made.
