On this paper, fluid analysis scheme is developed which can apply complex shapes easily with triangle mesh and can deal with both compressible flow and incompressible flow accurately and with low memory consumption using adaptive mesh refinement (AMR). To verify the effectiveness of this scheme, problems of shock waves peculiar to compressible flow and vortices peculiar to incompressible flow were analyzed. The results show this scheme can deal with the different properties of fluid compressibility and incompressiblity accurately and AMR plays the great role for efficiency of computation to compressible flow and incompressible flow both.
