Abstract:
1. A structural analysis apparatus, comprising: a storage for storing a result of an analysis of a mesh model; an iso-surface creation section that creates a field iso-surface from an analysis result of a mesh model, using the mesh model obtained by dividing a model into meshes to perform analysis of displacement or stress; a detailed mesh model creation section that uses the field iso-surface created by the iso-surface creation section to create a detailed mesh model which is a part of the mesh model and a characteristic part of the mesh model; an analysis section that uses the analysis result of the mesh model stored in the storage to perform analysis of the detailed mesh model created by the detailed mesh model creation section; and an analysis evaluation section that evaluates the analysis result of the detailed mesh model based on the analysis result obtained by the analysis section, and analysis result of the mesh model; wherein the detailed mesh model creation section includes: a first detailed mesh model creation section that creates a first detailed mesh model with the same mesh size as that of the mesh model; and a second detailed mesh model creation section that creates a second detailed mesh model with a finer mesh size obtained by reducing the mesh size of the first detailed mesh model to a predetermined size, the analysis section analyzes the second detailed mesh model based on a first boundary value obtained by the analysis of the mesh model to obtain a second boundary value of the first detailed mesh model and uses the second boundary value to analyze the first detailed mesh model, and the analysis evaluation section performs a first analysis evaluation based on the analysis result of the first detailed mesh model obtained by the analysis section, and analysis result of the mesh model; and a display displaying the evaluation of the analysis result of the detailed mesh model.
