Method and system for simulating flow of fluid around a body

A system for simulating flow of fluid around a body, comprising:

• a mesh generating section for dividing a target domain of simulation into a plurality of computational unit domains named cubes and for generating an uniform number of Cartesian mesh elements named cells, in each of the cubes;
• a computation section for performing computation in the cubes in each computational step and for exchanging data between adjacent cubes after completion of each computational step;
• and
• a computation control section for controlling computation of simulation,
• wherein when the mesh generating section divides the target domain of simulation into cubes, division is repeated while a ratio between adjacent cube sizes is maintained in a certain range until cubes including a boundary between the body and the fluid, is small enough to obtain a desired resolution so that sizes of the cubes are appropriately determined according to a shape of the body.
