Title:
SIMULATION DEVICE, SIMULATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/246378
Kind Code:
A1
Abstract:
Provided is a simulation device for analyzing the behavior of a powder that includes a plurality of particles, that has: a first parameter acquisition unit that obtains first parameters including parameters pertaining to the powder; a second parameter calculation unit that course-grains a particle group comprising the plurality of particles and calculates second parameters, being parameters for one course-grained particle; and a course-grained particle behavior analysis unit that analyses the behavior of the course-grained particles on the basis of the first parameters and the second parameters. The second parameter calculation unit uses the solution for a characteristic equation and calculates the second parameters, said characteristic equation using the relationship between the elastic energy of the particle group and the elastic energy of the course-grained particles.
