Stage 6. Transfer the Lagrangian forces to the Eulerian grid:This stage can be regarded as the inverse of the Stage 3. In this stage, the forces that have been calculated at the immersed boundary points are transferred again to the Eulerian grid points of the fluid domain. This is accomplished through Eq. (10). At the end of this stage, at any Eulerian grid points the new local forces are obtained.
