The 2D remeshed vortex method with the Brinkman penalisation scheme is applied to the simulation of flow around 2D cylinder and foil at the Reynolds number Re=500. The dependences of the hydrodynamic forces on domain dimension, mesh size and time step are analysed. The results are compared with those obtained with the commercially available finite volume CFD solver CFX@. The computation time is also presented. It is observed that the remeshed vortex method does not suffer from the blockage effect, and thus is potentially suitable for the simulation of flow with far-field boundary conditions. However, it has only a first-order accuracy with regard to time step, and therefore needs a quite small time step to acquire reliable hydrodynamic forces.
