Abstract
As one of the system useful for planning underground repositories, such as radioactive waste disposal facilities, we develop a groundwater flow analysis system using the voxel analysis method. This paper shows an example of issues of mesh generation in the groundwater flow analysis using the conventional finite element method. Use of the voxel analysis method solves the issues and improves the analysis efficiency. The paper also discusses an influence of the voxel mesh with jaggy surface upon the accuracy of analysis results.
