Abstract
An integrated technology is developed for the numerical simulation of the aerodynamics of moving bodies described by the immersed body method on unstructured meshes. The calculation accuracy is enhanced by the dynamic adaptation of the meshes. The method of grid adaptation is based on the technique of the redistribution of nodes implemented through solving an additional differential equation of the grid motion. This method enables retaining the original grid topology and does not incur a significant increase in computational costs. The technology is developed for 2D formulations and verified on model problems.
