Hi everybody

I have rather a fundamental question. What I understand from its description is when I use the Connolly task for a polymer, the probe scans the cavities where it can fit. If this is true, the minimum volume of an isolated free volume element should not be smaller than the probe volume. However, when I segragete free volume elements, I see that there are several elements (segragates) with sizes much smaller than that of the probe, and the smallest volume is equal to the cube of the grid size. E.g. if the grid size is 0.4 A, then the size of the smalles free volume element is 0.4^3, even though the probe radius is 1 A.

What do I miss here?

Thanks
