Abstract

The overset unstructured grid method is extended to multiple bodies that are in contact with each other, and the treatment of nodes in the overlapping regions of two bodies in contact is discussed In detail. The developed overset unstructured grid method is applied to the following cases: ONERA M5 body/wing, ONERA M6 store separation, and the National Aeronautical Laboratory (NAL) experimental supersonic airplane/booster separation. In each case, there are two bodies in contact, and the calculation is performed with the Euler code. The calculation results clearly show smooth transitions of the contour lines between two bodies. In the ONERA M6 and NAL airplane/booster cases, a simulation of separation from the connecting configuration is performed.
