Detailed Description

Blocked 2-D boundary condition solver for grids.

This class constrains the velocity field by projecting the flow to the blocked representation of the collider. A collider is rasterized into voxels and each face of the collider voxels projects the velocity field onto its face. This implementation should pair up with GridSinglePhasePressureSolver3 since the pressure solver assumes blocked boundary representation as well.
