Is your proposal related to a problem?
To calculate the interaction force between the fluid and solid obstacles, the Moment Exchange Algorithm (MEA) for Bounce Back Boundaries can be used. It's currently not implemented.
Describe the solution you'd like
Implement the MEA for BB Boundary Conditions. It sums up all momentum crossing the boundary in one timestep. This can be used to calculate the force acting on the obstacle, or to calculate Drag- and Lift-Coefficients.
Describe alternatives you've considered
There are modified MEAs and a DRTT method proposed by several people. But basic MEA is probably a good start.
Additional context
This is related to Issue #270 and can be implemented for all three variants of Bounce Back BCs: Fullway, Halfway, Interpolated.
