The base of the arrow represents the location INSIDE the fluid domain. As far as I can tell all those arrows have there bases INSIDE the fluid domain. Those vectors seem fine to me. yaseen wsu likes this.

the result was converged with (10^-4 residual) but that location is jump where air with water are mixed at the end.
