| DESCRIPTION: | RIPPLE is a two-dimensional, transient, free surface incompressible fluid dynamics program. It allows multiple free surfaces with surface tension and wall adhesion forces and has a partial cell treatment which allows curved boundaries and interior obstacles. |

| METHOD OF SOLUTION: | RIPPLE simulates incompressible flows with free surfaces using the volume-of-fluid (VOF) algorithm. This technique is based on the use of donor-acceptor differencing to track the free surface across an Eulerian grid. The complete Navier-Stokes equations in primitive variables for an incompressible fluid are solved by finite differences with surface tension and wall adhesion included. Optionally the pressure equation can be solved by a conjugate residual method rather than the successive overrelaxation (SOR) method. |
| COMPUTER: | SUN |
| OPERATING SYSTEMS: | UNIX |
| UNIQUE FEATURES: | RIPPLE is highly structured so that individual components may be easily modified to fit specific problem requirements or to accept subsequent code upgrades. |
| OTHER PROG/OPER SYS INFO: | RIPPLE contains calls to several system-dependent plotting routines and a time limit routine. These are not included, and users must supply their own equivalent routines. RIPPLE can run many problems without modification, but a specific application may require changes to the logic for special inflow or outflow ports, complicated geometries, or unusual conditions. These are accomplished by using the UPDATE utility. |
