slide_geometry index geometry_entity geometry_entity_index

This record makes material to slide over the geometry specified by geometry_entity geometry_entity_index. Velocities normal to that direction are not allowed.

This option comes handy when it is a priori known at which nodes sliding will occur, which is typically the case in an Eulerian calculation, or if deformations are small. Otherwise, contact conditions should be used (see contact_geometry etc.).

Optionally slide_friction can be specified.
