Coarse-grained particle model elongation breaking determination system, coarse-grained particle model elongation breaking determination method, and program

Abstract

To provide an elongation breaking determination technique of a coarse-grained particle model capable of quantitatively determining a breaking time point.SOLUTION: A system includes: a first coupling length acquisition section 11 that acquires a coupling length group of all coupling pairs in balancing processing in a state where processing of extending a coarse-grained particle model D2 is not performed for each type of a particle chain as a first coupling length group; a second coupling length acquisition section 12 that acquires the coupling length group of all coupling pairs in the balancing processing after the processing of extending is performed for each type of the particle chain as a second coupling length group; an abnormality degree calculation section 13 that calculates an abnormality degree of the coupling length of each coupling pair in the second coupling length group with respect to the first coupling length group for each type of the particle chain; a maximum abnormality degree calculation section 15 that calculates a maximum abnormality degree in a plurality of calculated abnormality degrees for each type of the particle chain; and a determination section 14 that performs determination processing for determining whether a coarse-grained particle model D1 is broken on the basis of the maximum abnormality degree calculated for each of a plurality of types of particle chains.SELECTED DRAWING: Figure 12
