Droplet impact on a solid surface
 
hi
im modeling splash of a droplet on a solid surface via fluent in 2d. the problem is shape of my droplet changes to something strange (upper half of droplet goes faster and disappears into other side of it) and it seems that the conservation of mass violated.
i changed mesh, solver model or controls, nothing helped. how can i achieve this?

Use explicit method and geo reconstruct scheme to advect it. It diffuses out because it seems time step is too large for it.

Or simply try smaller times steps.
