Fluid "outflow", is there a way?

[guismo]

Hi, I'm trying to create what would be understood in blender simulator as an "outflow". A mesh that works like the PHXSource, but instead of adding fluid to the scene it would remove it, as if it was a hole in space. Is there a way of doing this? I tried setting discharge to a negative number but it generates fluid. Or is my thinking wrong?

Thanks for any direction.

Negative discharge is the way to go. Can you share a screenshot of the setup and the source settings? Also, is the emitter solid or non-solid?

It's solid. I don't have access to an image service right now and it seem that the forum doesn't allow uploads. But it's a solid object and I tried both brush and inject. Brush just creates the volume as fluid at -100 as if it was 100 and -50 as if it was 50. Inject does something crazy that i'm not quite sure what it is.

Very strange - if the object that the source emits through is solid (set from the right click phoenix properties of the object), then brush and discharge should not matter and the result will be the same regardless of which one you choose - the emitter will create velocities going out of its surface for positive Discharge, and going into its surface for negative Discharge.

Also, are you using liquids? In this case, are you using the PHXLiquid source, or the standard PHXSource?

Regarding uploading to the forum, you must email support@chaosgroup.com for permissions, by default new users don't have any.

Right click on the object seems to be a 2.2 option. I'm using 2.1.1 right now. Yes, I'm using liquids and the PHXLiquid source.
Thanks, I'll send and email later on.

well, in 2.1 under "solid" we understand included in the interaction list
if the object is solid, negative discharge will consume liquid, if the object is not solid, you have to use a general purpose source (not liquid) set as brush source with discharge 100 and temperature 0. the temperature and the liquid share the same channel so this setup will clear the liquid in the entire volume of the object
