Computer-readable recording medium in which thermal hydraulic simulation program is stored, thermal hydraulic simulating device, and method for thermal hydraulic simulation

摘要

In the event of modifying analysis condition, after the simulation of a first time step carried out when the analysis condition is modified finishes and before the simulation of a second time step next after the first step starts, the modified analysis condition is referred and the simulation based on the modified analysis condition is carried out in the next time step.

主权项

1. A non-transitory computer-readable recording medium in which a thermal hydraulic simulating program that instructs a computer to carry out a simulation of a velocity field and/or a temperature field, the program instructing the computer to execute:
carrying out the simulation by solving a thermal hydraulic equation on the basis of an analysis condition in each time step; modifying the analysis condition; when the analysis condition is modified while the simulation is being carried out, storing data related to the modified analysis condition in a memory region; after completion of the simulation in a first time step being carried out at the modifying the analysis condition and before start of the simulation in a second time step after the first time step, referring to the data related to the modified analysis condition stored in the memory region; carrying out the simulation based on the data related to the modified analysis condition in the second time step; displaying a three-dimensional (3D) model representing a space including the velocity field and/or the temperature field on a monitor; and if a sliding mechanism having an opening ratio varying with sliding of the sliding mechanism is slid on the 3D model displayed on the monitor, modifying a resistance, serving as a resistance condition of the sliding mechanism and included in the analysis condition, in accordance to the opening ratio varied through the sliding.
