View Full Version : Blender Fluid - Obstacle Friction Question

Hi!

I'm new in blender, i'm impressed with it, it's a HUGE piece of software and it's well done.


I have a question relative to the fluid simulation, i've done a fluid simulation and i'm quite happy with the result but i want the liquid to be a little more crazy in my glass (it's a glass of wine...eternal test hehehe) and it seems that the obstacle (the glass) has too many friction, so:

can someone tell me how to control the friction of an obstacle?

Cheers and thanks!

Hi,

In the Obstacle change the settings to Free (Free-slip).

Link with some information: Blender Manual: Physics - Fluids (http://wiki.blender.org/index.php/Doc:Manual/Physics/Fluids)

Hope that helps.

Thanks for the answer Mordachai.

I knew about the Free-slip but i mean if i can define an specific friction for the obstacle, so i can have a kind of surface that slips the water well and another that makes the water stop, but all in the same simulation and with intermediate values of friction.

Cheers and thanks :D

YES! I hope you get an answer for this because it's the same thing I need as well, my obstacle is getting the water stuck to it too long - it doesn't slip off quick enough and it looks to thick on the obstacle.

If setting the obstacle to "no slip" is too sticky, and "free" is too slippery, you could always try "part" and adjust the value between 0 (= no slip) and 1 (=free slip).

Okay I'll try that thanks.
