Apparatus, and method for generating analytical model, and recording medium in which program for generating analytical model is stored

A method for generating an analytic model of an object shape model, said analytical model being used for numerical analysis, comprising the steps of:

• (a) generating a detail mesh model of the object shape model based on the object shape model;
• (b) generating a maximum outer shape mesh model corresponding to an outline of the object shape model based on the object shape model;
• (c) generating a basic wall-thickness region, which extends inside the maximum outer shape mesh model from at least a part of surfaces of the maximum outer shape mesh model and which has a predetermined thickness;
• and
• (d) generating said analytical model by using a result of overlaying the detail mesh model with the basic wall-thickness region.

A computer-readable recording medium in which a program for generating an analytical model of an object shape model, said analytical model being used for numerical analysis, wherein said program instructs a computer to function as:

• a detail-mesh-model generating section which generates a detail mesh model of the object shape model based on the object shape model;
• a maximum outer shape mesh model generating section which generates a maximum outer shape mesh model corresponding to an outline of the object shape model based on the object shape model;
• a wall-thickness-region generating section which generates a basic wall-thickness region, which extends inside the maximum outer shape mesh model from at least a part of surfaces of the maximum outer shape mesh model and which has a predetermined thickness;
• and
• an overlaying section which generates said analytical model by using a result of overlaying the detail mesh model with the basic wall-thickness region.
