Vertex Commands GEOMETRY COMMANDS 2-2 © Fluent Inc., Jul-04 2.1 Vertex Commands GAMBIT geometry vertex commands allow you to create and manipulate vertices. The command set includes the following commands: vertex align vertex blend vertex check vertex cmove vertex connect vertex convert vertex copy vertex create vertex creflect vertex cscale vertex delete vertex disconnect vertex modify vertex move vertex move virtual vertex reflect vertex scale vertex summarize The following sections summarize the purpose, form, and parameters associated with each of the commands listed above.
GEOMETRY COMMANDS Vertex Commands © Fluent Inc., Jul-04 2-3 2.1.1 vertex align Purpose To reposition one or more vertices and/or to reorient any connected geometry. General Form vertex align vertex1 [ vertex2 ... ] translation vertex1 vertex2 [[ rotation1 vertex1 vertex2 [ stretch ]] [ rotation2 vertex1 vertex2 ]] [ connected ] Example vertex align "vertex.15" translation "vertex.15" "vertex.4" \ rotation1 "vertex.11" "vertex.5" rotation2 "vertex.16" \ "vertex.6" connected Keywords Keyword Description connected Specifies aligning all geometry connected to the vertices rotation1 Specifies the rotation vertex pair (vertex1 , vertex2) rotation2 Specifies the plane-alignment vertex pair (vertex1 , vertex2) stretch Specifies scaling all geometry by distance ( t 1 , r 1 ) and distance ( t 2 , r 2 ), where translation vertex pair = ( t 1 , t 2 ) and rotation vertex pair = ( r 1 , r 2 ) translation Specifies the translation vertex pair (vertex1 , vertex2)

Vertex Commands GEOMETRY COMMANDS 2-4 © Fluent Inc., Jul-04 2.1.2 vertex blend Purpose To set blend parameters for one or more vertices. NOTE : This command is used in conjunction with the volume blend command. General Form vertex blend vertex1 [ vertex2 ... ] [ bulge real ] [ setback real ] Example vertex blend "vertex.2" setback 2 Keywords Keyword Description bulge Specifies the shape parameter ( real ) of the blended face Range: 0 ° real ° 2 setback Specifies the distance ( real ) to set back a blended corner from the original vertex location Range: real > 0
GEOMETRY COMMANDS Vertex Commands © Fluent Inc., Jul-04 2-5 2.1.3 vertex check Purpose To check specified vertices with respect to topological and geometric validity. General Form vertex check vertex1 [ vertex2 ... ] [ topology ] [ geometry ] Example vertex check "vertex.2" topology Keywords Keyword Description geometry Evaluates the specified vertices with respect to model tolerances.
