A technique for solving rigid-body impact on a viscous, incompressible medium is presented. The numerical scheme is adapted from the Marker and Cell (MAC) method developed to solve problems involving time-dependent motion of a viscous, incompressible fluid in two-dimensional space. As the pressure end velocity fields are computed throughout the flow field, the solution gives the force and displacement time history of the rigid-body during the impact phase. In conjunction with this, through a system of marker particles, the changes in configuration of the viscous medium on impact can be studied. With a "movie frame" (incremental time) approach, computational experimentation may be performed to examine in detail the phenomena of impact.
