Wouldn't a velocity only wall kinda defeat the point? Pressure and velocity are very closely linked, if you create pressure, you get velocity. If you create velocity (eg. WIND tool - check the pressure display), get pressure. So a velocity only wall would defeat the point, as you'd still get pressure from all the air movement, but a pressure and velocity blocking wall wouldn't work, as particles would get stuck.
a) we already established that b) as i said in my last post you can generate velocity without pressure c) we've been discussing ways to have a pressure-blocking-but-allows-velocity wall
EDIT: d) even if we hadnt already said all you said that wouldnt "solve" anything, just tell us we have to keep thinking.....
It'd work if the particle was travelling down, because then it would have gravity to keep it moving, but left, right and most definitely up might have some trouble
I probly should of said Particle Wall, because it seems that people keep thinking that moving particles should pass through. <------ NO.<br/>It's no ment for moving particles at all, its ment for electronics. Wifi gets destroyed at a pretty low pressure, so if we Eliminated that pressure, but still allowed the Wifi, metal, instant, and other particles, then we WOULD NOT have to use 8 WALLS to surround a single wifi to protect it from the tremendous pressure just surrounding it.
It's not supposed to be a Velosity Wall, or Pressure Wall (I know the title contridicts), it's supposed to be a Particle Wall - Blocks pressure, Allows Particles - Great for protecting Pressure-Sensitive Things!
