CONTROL METHOD FOR THREE-DIMENSIONAL MESH SYSTEM FOR PARALLEL CALCULATION

摘要

PPROBLEM TO BE SOLVED: To uniformize a load in each processor, to optimize the use of a storage area, when the reactor core of a three-dimensional mesh system is calculated in parallel by the single or the plurality of processors, and to simplify a program, when analyzed by a Red/Black method. PSOLUTION: When the three-dimensional mesh system of the reactor core is defined in a nuclear reactor of an evaluation object, a horizontal face is divided in about 1/4 of a fuel assembly, and a block divided properly and a detail mesh constructed inside the block are defined vertical, and to be controlled separately. The division number, for constructing the detail mesh inside the block, is set even numbered in any direction, when analysis is to be conducted by the Red/Black method. PCOPYRIGHT: (C)2008,JPO&INPIT
