Table 1.

Detailed description of the virtual simulation space. The simulations on ‘0.5 mm grid’, ‘1.0 mm grid’ and ‘2.0 mm grid’ were performed using fixed resolution grids. ‘0.5&1.0 mm grids’, ‘0.5&2.0 mm grids’ and ‘1.0&2.0 mm grids’ denote the simulation conducted using multi-resolution grids. All represented in isotropic voxels.
