Boundary particle search system, boundary particle search device, control method, and program

摘要

PPROBLEM TO BE SOLVED: To search for a particle at the boundary of an analysis model used in numerical analysis using a particle method and the like. PSOLUTION: A boundary particle search system includes: a search reference particle setting part which extracts one or more particles in the boundary from the positional coordinates of all the particles that constitute the analysis model and makes the search reference particles; a vector setting part which sets a search direction vector indicating the direction of searching using as a start point the search reference particle extracted by the search reference particle setting part; a region particle extraction part which extracts the other particle in the region defined on the basis of the positional coordinates of the search reference particle; a vector calculation part which creates each positional vector of each particle in the region extracted by the region particle extraction part in relation to the search reference particle and calculates the size of the positional vector and the angle of the positional vector with the search direction vector set by the vector setting part; and a boundary particle determination part which determines the boundary particle by the size and angle of the vector calculated by the vector calculation part.
