wall resolution command

Syntax

wall resolution keyword

Primary keywords:

full    none    reduced

Modify the contact-resolution strategy as outlined in the “Faceted Walls in PFC” section. By default, the resolution strategy is set to the reduced state. In all cases, contact activity based on contact with active/inactive facet sides (see wall active-sides) is determined.

Note

Eliciting this command does not result in an automatic “cleaning” of the model state.

full

The contact resolution procedure for contacts with facets is at its full state. This means that in addition to the associative checks for contact activity, the sliver penetration conditions are checked, and the cutoff angle becomes active for contact-state information propagation for convex and concave facet intersections. Proximity contacts may result.

none

No contact resolution is undertaken. This is the most computationally efficient method for contact resolution but may result in many more active contacts, reducing overall performance. Additionally unexpected responses may occur for wall geometries that are intended to be smooth.

reduced

The contact resolution procedure for contacts with facets is reduced (the default setting). The reduced contact resolution does not check for sliver penetration conditions nor is contact-state information propagated. The associative logic is applied to determine the contact activity state, though. This state is more computationally efficient than the full state.
