It is a special algorithm to navigate in a regular voxelised geometry. It includes an option to skip frontiers between voxels when they have the same material i.e. "replacing group of voxels with a smaller number of larger voxels". '''G4RegularNavigation''' class is the default setup for this tutorial. To run with the default settings simply run macro run.mac. | It is a special algorithm to navigate in a regular voxelised geometry.
