Vector Collectors

Vector collectors collect and organize vectors. Vector collectors are created, edited, and deleted from the Model browser and are shown under the VectorCollector folder.

Vectors can be organized into a vector collector using the Organize panel. Every vector must be organized into one, and only one, vector collector and therefore are mutually exclusive to a vector collector. Newly created vectors are automatically organized into the current vector collector.

The current vector collector is shown bold in the Model browser. The current vector collector can be set using the Model browser context menu on a selected vector collector within the VectorCollector folder. Vector collectors can also be card edited using the Model browser context menu on selected vector collectors.

Vector collectors have a display state, on or off, which control the display of all vectors organized within the vector collector in the graphics area. The display state of a vector collector can be controlled using the icons next to the vector collector in the Model browser.

Vector collectors also have an active and export state. The active state of a vector collector controls the display state of the vector collector and the listing of the vector collector in the Model browser and any of its views. If a vector collector is active, then its display state is available to be turned on or off and it is listed in the Model browser and any of its views. If a vector collector is inactive, then its display state is turned off permanently and it is not listed in the Model browser or any of its views. If a find operation "finds" an inactive vector collector, that vector collector will automatically be set to active.

The export state of a vector collector controls whether or not that vector collector and all vectors organized within the vector collector are exported when the custom export option is utilized. The all export option is not affected by the export state of a vector collector. The active and export states of vector collectors can be controlled using the Entity State browser.

Operations performed on a vector collector affect vectors within the vector collector. For example, if you delete a vector collector, the vectors within the vector collector are also deleted.

The data names associated with vector collectors can be found in the data names section of the HyperMesh Reference Guide.

Solver Card Support for Vector Collectors

Vector collectors are used to group vectors.

•	For Nastran, vectors can be used to define orientation directions for some 1D elements and forces, or to define the SNORM card.

•	For orientation vectors, it is not necessary to load any card image data onto the vector collector.

•	For SNORM vectors, you must load the SNORM card image onto the vector collector. Once this is done, all vectors organized into that vector collector will write out as SNORM vectors to the Nastran bulk data file.

Supported Card	Solver Description	Supported Parameters	Notes
SNORM	Defines a surface normal vector at a grid point for CQUAD4, CQUADR, CTRIA3, and CTRIAR shell elements.		There is no card image associated with the collector. In order to view the actual SNORM cards, each vector must be individually card edited. Loading the SNORM card image onto the collector assigns the SNORM type onto all of the vectors contained in that collector.
