摘要

An analysis apparatus 10 is an apparatus for analyzing a motion of a deformable body and comprises a model generation unit 12 for generating a model of the deformable body provided with virtual particles whose centers constitute vertexes of a tetrahedron dividing the deformable body, a first force calculation unit 13 for calculating a first force occurring between the particles nonadjacent to each other provided on a surface of the deformable body, a second force calculation unit 14 for computing a stress occurring in the tetrahedron dividing the deformable body and calculating a second force occurring in each particle from a plane dividing the tetrahedron and the stress, and a particle position updating unit 15 for taking a sum of the first and second forces so as to compute a force occurring in each particle and solving a motion equation so as to update a position of each particle.

1. An analysis apparatus for analyzing a motion of at least one deformable body, the apparatus comprising:
model generation means for generating a model of the deformable body provided with a plurality of virtual particles whose centers constitute vertexes of a tetrahedron dividing the deformable body; first force calculation means for calculating a first force occurring between the particles nonadjacent to each other provided on a surface of the deformable body in the model generated by the model generation means; second force calculation means for computing a stress occurring in the tetrahedron dividing the deformable body in the model generated by the model generation means and determining a plane dividing the tetrahedron, so as to calculate a second force occurring in each of the particles constituting the tetrahedron from the computed stress; and particle position updating means for taking a sum of the first force calculated by the first force calculation means and the second force calculated by the second force calculation means for each particle, so as to compute a force occurring in each particle, and solving a motion equation according to the computed force, so as to update a position of each particle.
