Hi I'm doing a simulation with a software Gerris and I'm trying to simulate the oscillation of water drop due to viscosity and surface tension with gravity acting downward the problem is symmetric along y axis and it should oscillate quite a few times which was observed in the experimental videos but the oscillation is being deviated as time proceeds these are the simulation output as time
