wiggle

Submitted by dnojiri on Thu, 04/26/2012 - 11:44

If I have a cylindrical container created like this:
fix zwalls all wall/gran/hertz/history 1 0 zplane 0 0.3 1
fix cylinder_wall all wall/gran/hertz/history 1 0 zcylinder 0.052 1

should I expect the same effect on the particles if I wiggle the "region" than If I wiggling the two fixes written above with the same amplitude and period?

What do you mean with 'if I wiggle the "region"' ? If you "wiggle" the wall fixes, the wall will wiggle. If not, it will not "wiggle"

Hello!
The wall fixes are inside a previously created region:
region reg cylinder z 0 0 .052 -0.01 .3 units box

is:
region reg cylinder z 0 0.052 -0.01 .3 units box wiggle 0 0 0.01 0.15

the same as?:
fix zwalls all wall/gran/hertz/history 1 0 zplane 0 0.3 1 wiggle z 0.01 0.15
fix cylinder_wall all wall/gran/hertz/history 1 0 zcylinder 0.052 1 wiggle z 0.01 0.15

Thanks!

No, it's not the same. The logic is that the wall does not refer to the region - so it can't be influenced by whatever settings you make for this region
