wall active-sides command
Syntax
- wall active-sides keyword <range>
-
Specify which side(s) of facets are active. An inactive side will allow balls or pebbles to pass through it without being repelled. Both sides of all facets are active by default. The range is applied to facets. Use the set range element to filter by walls. One can visualize the normal vector with the wall arrow plot to assess the orientations of facet normals.
Note
No effort is made to mitigate large forces that develop when balls or pebbles migrate from the inactive to active sides of walls. Thus large velocities may result in these situations.
- both
Set both sides as active.
- bottom
Set the side opposite the direction of the facet normal vector as active.
- neither
Set both sides as inactive. No forces will occur.
- top
Set the side in the direction of the facet normal vector as active.
