| A special case is MEDIUM_VECTOR with tabulated material (material type 1), where we say to Gsvit that there are only few materials in our computational volume and therefore GSvit does not need to allocate material parameter fields for every voxel. This can save some memory (a quarter of it, approximately), however all the calculations remain the same. See the parameter file documentation for more details. | A special case is MEDIUM_VECTOR with tabulated material (material type 1), where we say to Gsvit that there are only few materials in our computational volume and therefore GSvit does not need to allocate material parameter fields for every voxel.
