Аннотация:An integrated technology is developed for the numerical simulation of the aerodynamics ofmoving bodies described by the immersed body method on unstructured meshes. The calculationaccuracy is enhanced by the dynamic adaptation of the meshes. The method of grid adaptation is basedon the technique of the redistribution of nodes implemented through solving an additional differentialequation of the grid motion. This method enables retaining the original grid topology and does notincur a significant increase in computational costs. The technology is developed for 2D formulationsand verified on model problems.
