Abstract

In order to simulate relative motion of bodies and to increase flexibility in grid generation of complex configurations, an overset grid technique can be used to couple overlapping grid blocks by interpolation of the flow data. Parts of a component grid that overlap a solid body, have to be excluded from the flow computations. In the previous implementation within DLR’s flow solver TAU this is realized by a hole cutting procedure based on hole definition geometries provided by the user. In this work an automatic hole cutting procedure is implemented in the TAU code, which is based on the intersection of grid edges and surface cells to detect the grid points inside of the body and supports overlapping surface grids. The presented method is demonstrated for two test cases.
