Abstract

In the present study, an intelligent computational grid is introduced which adapts itself to the body displacements in the computational domain by regular and systematic changes of the nodes. Configuration of the introduced grid is based on defining separate zones around the body for Rotational and translational motions. Therefore, the ordinary problems in available moving grids which try to keep the nodes stable, such as: reduction of the grid quality, the need for regenerating the grid overally or locally, interpolation, or data transfer between different parts of grid are decreased to a great extent. Defining a three-dimensional Moving-Grid and the lack of limitations on the size of Rotation or translation of body are also amongst the advantages of this method. Then, changes made following the body Rotation/translation and reformation of the grid through changes in its connection for a rectangular wing with NACA0012 airfoil was shown. Finally, to validate the correct performance of the introduced Moving-Grid method, the three-dimensional Unsteady form of the Euler equations was solved. Several test cases were solved and the results were compared with reliable experimental and numerical. Results, showing relatively close agreements
