CylindricalRegion (Node)
Constructs a cylindrical region
Overview
The GeneralRegion node generates a region encapsulating the free or void space within a box - it is therefore particularly suitable as a region for the insertion of new molecules by an

node.
Description
The GeneralRegion node assesses the current contents of a configuration and locates “free volume” into which molecules can be added. Volume is excluded based on the proximity of existing atoms in the configuration - a volume element is excluded if any atom is within the tolerance distance specified of its coordinate centre.

Cubic voxel length to use when partitioning space. A smaller voxel size gives a more fine-grained region, at the expense of memory and speed. |
