Title:
ANALYSIS METHOD, ANALYZER AND PROGRAM
Document Type and Number:
Japanese Patent JP2022109696
Kind Code:
A
Abstract:
To provide an analysis method, an analyzer and a program, capable of achieving an effect of sufficiently reducing computational complexity, while sufficiently reflecting a state of a flow field even if anisotropic renormalization is performed on a particle system of an analysis object.SOLUTION: An analysis method performs renormalization on a particle system of an analysis object by a degree of renormalization determined for each of three directions orthogonal to one another, according to a shape of a flow field of the particle system. With regard to the particle system after the renormalization, an equation of motion governing the particle system is numerically solved. When performing the renormalization, the number of particles is reduced according to the degree of the renormalization, the shape and a volume of the flow field are not changed before and after the renormalization, but each mass of the particles is increased according to the degree of the renormalization. Furthermore, an interaction potential between the particles is transformed according to the degree of the renormalization of each of the three directions.SELECTED DRAWING: Figure 3
