The paper considers the reconstruction of body geometry basing on discrete elements of computational domain. This problem arises when numerically simulating flow around solid bodies with the use of immersed boundary method. The analysis of possible techniques of reconstruction is presented. Based on them the method of space reconstruction of bodies prescribed on unstructured meshes is built and used for the computation of model problems.
Keywords: numerical simulation, immersed boundary method, space triangulation, caching of data.
