create boundary with walls

Asked by Mahdeyeh

Hello there
I want to create a boundary for volume of my simulation with 23 walls. How I can give coordinate to walls?
for example one of the walls has these coordinates: (0,2,0) (0,-2,0) (0,2,4) (0,-2,4)

How I should write code for creating this boundary
Should I use this code: yade.utils.wall? How write coordinate in this code?

thanks

Hello,

yade Wall shapes are infinite zero thickness planes parallel to xy, yz or zx planes. So you might use them if the extent to infinity is not a problem.

Otherwise you may use Boxes:
###
w = box(center=(0,0,2),extents=(0.1,2,2)) # [1], 0.1 is to have non-zero thickness in x direction
O.bodies.append(w)
###

In any case, you have to use corresponding Bo1 and Ig2 functors [2]

cheers
Jan
