PURPOSE:To reduce the capacity of a memory and to shorten processing time by discriminating an area where fluid is absent, an area where a solid moves and the area of fluid and permitting the moving solid to satisfy the continuous condition of a system in the certain area. CONSTITUTION:The boundary condition of the system including the moving condition of the solid is stored, and (b) the system is divided into the calculation area where fluid is absent, the calculation area including the moving solid and the calculation area only by fluid in accordance with the stored boundary condition at prescribed time. (c) Equations satisfy the continuous condition of fluid in the system are generated for the respective discriminated calculation areas ((k), (l) and (m), and (d) the variables of the system, which satisfy the generated equation, are obtained as solutions. Then, they are stored as the respective variables of the calculation areas. Prescribed time is changed and the stored variables are set as the variables of the system at new time, and the processing of (d) from (b) is repeated so as to output the variables of the system for respective prescribed time. |
