A Voxel-Based Approach to Structural Analysis That Includes Consideration of Contact Conditions

A voxel model, which consists of minute cubic cells called voxels to express the shape of an object, can now be generated automatically from CAD data. Moreover, advances in high-speed computational techniques have made it possible to perform a structural analysis using such a voxel model. This paper presents some high-speed computational techniques to realize the analysis in practice and a method to treat a contact condition on the jagged surface that characterizes a voxel model to further expand the scope of application.
