PURPOSE: To shorten calculation time in thermal fluid analysis by a parallel arithmetic processing by dividing the internal part of a thermal fluidized object into plural partial areas and using the suitable analysis programs of analysis methods for the respective partial areas. CONSTITUTION: An analysis area is automatically divided into the plural partial areas 4-1-4-7 in the inside of an electronic computer. One or plural arithmetic processors are allocated to the respective partial areas and calculation is performed. At the time, the analysis of the different analysis programs or the different methods is performed corresponding to states for the respective partial areas. Also, for the respective partial areas, the number of variables to be analyzed and the number of the arithmetic processors are changed as well. That is, the analysis method capable of highly accurately calculating local distribution is used for the partial area where the variable of a temperature or the like rapidly changes and the analysis method capable of calculating overall distribution at a high speed is used for the partial area where the change is small. Since unrequired calculation is eliminated, the calculation time is shortened. Also, since a data transfer amount is reduced, data transfer time is shortened. |
