Fluid , surface emission and colide

[user_deleted]

hello

I have a 3d fluid container and a surface witch emitts fluid contents ( mostly density )...  to create a dust storm

I want that dust collides with its emitter (the ground surface) , like desert dust that hits the ground.

when I do a copy of the ground and make the fluid container collide with it,  the dust is kinda trapped untill I move the copied ground plane far below ..

but I don't want that .. I want nearly exact contact between dust and ground, with the mentioned method I loose lots of a space and doesn't look right to me...

any ideas please?

thank you in advance

Hi MM

What you have described is confusing.  

I did a simple test:
yellow box = fluid collider
Green selected grid = emitter
Small blue fluid container

Fluid is simulated and emitted from plane, bouyancy is negative, fluid flows downwards hits ground and dissapates.

If you have a "cube" emitting your fluid/density, you need to create a second one - do not use a plane - use a closed surface - a cube as the collider.  Put the top of the cube where your ground is supposed to be.

It should work.
