I wanna analyse a sloshing caused by sudden braking of a truck traveling at 20m\/s.  Like the videos on YouTube, I use VOF method and Piso solver. Unlike videos, I wrote that equation of gravitational X acceleration IF(t<=1[s],20 [m\/s^2],0[m\/s^2]) . It means the truck velocity starts from 20 m\/s at t=0 and it breaks until 1sec. Then \u0131t’s velocity is 0. And Y acceleration -9.81 Z acceleration is 0. <\/p>\n

But \u0131n the 0.49 flow time I get this result. Sloshing shouldn’t be like this. Did I miss somethings?<\/p>\n
