Detailed Description

Abstract base class for 2-D boundary condition solver for grids.

This is a helper class to constrain the 2-D velocity field with given collider object. It also determines whether to open any domain boundaries. To control the friction level, tune the collider parameter.

Parameters

newCollider	New collider to apply.
gridSize	Size of the velocity grid to be constrained.
gridSpacing	Grid spacing of the velocity grid to be constrained.
gridOrigin	Origin of the velocity grid to be constrained.
