1. An analysis device that analyzes an object with a predetermined shape, comprising:
- a computer with a processor and a memory;
a pre-positioned creation unit that creates, using the processor, an ingot particle system, larger than a particle system describing the object, and including a plurality of particles, wherein a relaxation calculation is performed, using the processor, for the plurality of particles included in the ingot particle system;
a region specifying unit that specifies, using the processor, a region with the predetermined shape in the ingot particle system created by the pre-positioned creation unit as the particle system describing the object; and
a numerical calculation unit that numerically calculates, using the processor, a governing equation governing motions of particles in the particle system describing the object.
