Abstract

An analysis device that analyzes an object with a predetermined shape is provided which includes a pre-positioned creation unit that creates a system including a plurality of particles, a region specifying unit that specifies a region with the predetermined shape in the system created by the pre-positioned creation unit as a system describing the object, and a numerical calculation unit that numerically calculates a governing equation governing motions of particles in the system describing the object.

Claims

1. An analysis device that analyzes an object with a predetermined shape, comprising:

a pre-positioned creation unit that creates a system including a plurality of particles;

a region specifying unit that specifies a region with the predetermined shape in the system created by the pre-positioned creation unit as a system describing the object; and

a numerical calculation unit that numerically calculates a governing equation governing motions of particles in the system describing the object.

2. The analysis device according to claim 1, wherein the pre-positioned creation unit includes

a regular system creating unit that creates a system including a plurality of particles regularly arranged, and

a changing unit that changes the system created by the regular system creating unit on the basis of the governing equation governing the motions of particles in the system, and

wherein the region specifying unit specifies the region with the predetermined shape in the system changed by the changing unit.

3. The analysis device according to claim 2, wherein the changing unit changes the system created by the regular system creating unit so as to cause the system to exhibit non-uniformity.

4. A simulation method of simulating a mechanical structure with a predetermined shape, comprising:

preparing a system including a plurality of particles and describing a state before the mechanical structure is formed in the predetermined shape; and

cutting and analyzing a system with the predetermined shape from the prepared system.

5. A computer program causing a computer to execute a process of analyzing an object with a predetermined shape, the process comprising:

creating a system including a plurality of particles;

specifying a region with the predetermined shape in the created system as a system describing the object; and

numerically calculating a governing equation governing motions of particles in the system describing the object.
