Image Based Modeling, Measurement and Analysis
VOXELCON
Analysis
Using voxel model created from CT-images or STL model, you can execute stress analysis, steady-state heat conduction analysis, and homogenization analysis etc.
Static Stress Analysis
You can analyze a complicated model easily without troublesome mesh generating. Boundary conditions can be set not only to voxel model but to STL model.
Steady-state heat conduction analysis/ Thermal stress analysis coupled with heat conduction analysis.
You can excute "steady-state heat conduction analysis", and "Coupled thermal stress analysis".
Unsteady Heat Conduction Analysis
Multi-Scale Analysis by the Homogenization Method
Based on the theory of homogenization method, VOXELCON can deal with the material which has a detailed micro structure compared to whole structure. ( e.g. Composite Material and Porous Material )
Equivalent Physical Property
Based on the homogenization method, it can calculate equivalent physical-property values of composite materials or porous materials etc. The calculable physical-property values are as follows.
- Equivalent Elastic Coefficient
- Young's Modulus, Poisson's Ratio, Shearing Modulus - Equivalent Linear Expansion Coefficient
- Equivalent Thermal Conductivity
- Equivalent Permeability Coefficient
Localization
After analyzing macro structure (the whole structure) using the calculated equivalent physical property, you can evaluate stress distribution of any point. It's called "Localization".

Multi-Scale Analysis by the Mesh Superposition Method
You can get analysis result in detail by overlaying local fine meshes on a whole coarse mesh.
Topology Optimization
The stiffness maximization subject to the volume constraint is available. Of course, you can use models from CT-images.

Large Scale Model Analysis
It is possible to analyze also 100 million or more voxels by 64-bit machine.
In recent years, PC with tens of memory and 64 bit OS can be obtained easily.
If such machine resources are utilized, You can tackle large-scale analysis like 100 million voxels with PC.
The memory usage of 100 million voxels
-> about 25 GB (Static Stress Analysis)
