Search radius should be equal to the maximum between the narrow band size and the diameter of the circumcircle. This guarantees that, when the narrow band size is equal or less than zero, the levelset will be evaluated on the cells that intersect the surface and on all their neighbours.

Search radius should be equal to the maximum between the narrow band size and diameter of the circumcircle. This guarantees that, if the size of the narrow band is equal or less than zero, the levelset will be evaluated on the cells that intersect the surface and on all their neighbours.
This is the same behaviour of the octree patch and, as an example, generates the narrow band in the image below.
