Support method, recording medium, and design support device to calculate a volume of a three-dimensional model

摘要

A design support method includes: executing by a computer operations of: moving, in an arbitrary direction, a first particle that is placed at a position in an internal space of a three-dimensional model of a design target and has a diameter of a size; recording a movement trace of the first particle; and calculating a volume of a first spatial region formed by the recorded movement trace.

1. A design support method comprising:
executing, by a computer, operations of:
separating an internal space of a three-dimensional model of a design target into meshes, the three-dimensional model including structures;placing a first particle having a first diameter in a specified particle occurrence position of the meshes;moving, in a first arbitrary direction, the first particle in the meshes while classifying each of the meshes into a space or a component;recording a first movement trace of the first particle by checking a presence or an absence of the first particle in each of the meshes;placing a second particle having a second diameter different from the first diameter in the specified particle occurrence position of the meshes;moving, in a second arbitrary direction, the second particle in the meshes while classifying each of the meshes into the space or the component;recording a second movement trace of the second particle by checking a presence or an absence of the second particle in each of the meshes; andcalculating a first volume of a first structure of the structures by comparing the first movement trace and the second movement trace.
