Recently we introduced a function in PHITS to treat tetrahedral-mesh geometry. Tetrahedral-mesh geometry is a structure composed of combination of tetrahedrons and able to construct complex objects. Tetrahedral-mesh objects can be obtained by converting polygon data using mesh generation software such as TetGen. We also implemented a function in PHITS to export tally results into the format of the three-dimensional visualization software ParaView. TetGen is able to convert the polygon data into ParaView format. Together with these tools, three-dimensional analysis can be realized for PHITS simulation using a polygon objects.
