The “volumetric technique” for calculating force defines a cube surrounding the object which the force applied on it should be calculated. Is there any way to specify a spherical surface surrounding the object?
I have a nano-sphere. It is located in free space, but it is very close to other objects. It is not possible to define a cubic that encompasses only the sphere not the nearby objects. I was wondering if there is a way to define a spherical volume (or surface) around the sphere in the “volumetric technique”. I appreciate any comment.
Thank you in advance
