Large amplitude oscillation of a 2D liquid droplet

Pressure evolution for a large amplitude oscillation of a 2D liquid drop. The dash-dotted circle is the drop configuration in the beginning of the simulation. The spatial resolution is N = R/∆r = 400. Motion amplitude epsilon=a/R=1.

The simulation is performed with the RHOD-SPH model.
