Strange splash behaviour

[VIRTEK]

Hi, just preparing a simulation I notticed that the splah (green color in attached picture) dissapears in a very strange way out of the grid. Any idea? also, are the parameters acorrect for a hull simulation?
Thanks in advance.

Yup, you should increase the Outside Life - the parameter means that particles with age bigger than this one will be deleted when going outside the grid - this is the total age, and not the time since leaving the grid.
