Syntax

fix_modify <AtC fixID> mesh create_faceset <id> box <xmin> <xmax> <ymin> <ymax> <zmin> <zmax> <in|out> [units]

• AtC fixID = ID of fix atc instance

• mesh create_faceset = name of the AtC sub-command

• id = id to assign to the collection of FE faces

• box = use bounding box to define FE faces

• <xmin> <xmax> <ymin> <ymax> <zmin> <zmax> = coordinates of the bounding box that is coincident with the desired FE faces

• <in|out> = “in” gives inner faces to the box, “out” gives the outer faces to the box

• units = option to specify real as opposed to lattice units
