In this paper a finite element version of the direct Laplacian method is applied to flows around an oscillating body, using the arbitrary Langrangian‐Eulerian (ALE) formulation for the partial domain around the body. This numerical calculation has been successfully conducted for vortex‐induced, cross‐flow oscillations of a circular cylinder under the same conditions as for Anagnostopoulos and Bearman's experiment ( J. Fluids Struct. , 6, 39–50 (1992)), in which the Reynolds number ranged between 90 and 150, a regime where the vortex street is fully laminar. The numerical calculation results have been compared with the experimental data in order to check the calculational accuracy.
