particles sticking to walls

Submitted by VAJIHEH on Sun, 01/13/2013 - 23:18

Hi,

In my coupled simulation particles that contact with the walls escape from the domain after few collisions with the walls. I need the particles to stick to the walls as they hit the wall and stay there, and any particles that collide with them also to stick to them near the wall. I would appreciate if you can help me where to add this in the code. I was thinking of zeroing the COR. I appreciate any advise?

Regards,
Vajiheh

Hi,
i did something similar a few month ago. I decided to write a new fix to set the velocity of a particle in a given region to zero.
I uploaded the fix here for you.

It can be used to achive the first goal to stick the particles near to the wall. (just make reagions along your wall (hopefully not to complex?) and than use

fix fixLeft all set 1 0 0 0 region regLeft
