Particles From Velocity Field Hitting the bound even with a lot of room

[DesbiensAntony1997]

Hi! i do a particle effect made from a velocity field and i have a problem where my points kind of spot moving foward even if a have a large bounding box.

I've tried to make a wall clean up, but in the end result my points look like they are sticking on the bound hitself.

Hope that you guys can help out!

Thanks in advance!

I can't check your file, but if you're advecting particles by a simulated velocity field, either extend the simulated cache range and bounds of your velocity field or hand off the push to particle fields with an animated blend between the forces so they'll continue moving outside the velocity sim bounds.  Otherwise they'll just stop where there's no velocity data as you're seeing here

You mean changing the the Advection type by force? I don't really understand what you mean by pushing the fields with an animated blend with some forces.

I've played  a lot with the range of my bound and still it get stuck again.

You should be able to check my file now.

I meant keyframe the force of your advectByVolumes force off while keyframing a regular POP force on before your particles hit the boundary of your velocity field - there is no data beyond the bounds of a velocity field, so as soon as they reach whatever bound you set, they are going to stop.
