The initial volume-fraction profile is made up of two straight lines; and the two fluids, of equal densities are given equal and opposite velocities. The predicted profiles certainly show that the irregularity of the profile increases in amplitude. A 1-second period is considered, divided into 100 equal intervals a duct of 1m length is considered, with 20 equal intervals. The initial velocities are 1.0 m/s, in opposite directions. The initial values of r represent a symmetrical shallow roof (or trough). The cyclic boundary condition is activated. PHOTON (Autoplot) commands are provided at the top of the Q1 file.
