VIEW MESH

 

This command allows the user to display the mesh of selected parts of the model.

FEMGEN Command.
                 

VIEW MESH Part [Colour]

Part Colour Comments

Partname [RED] Displays the mesh of the named geometric

[ORANGE] part in the specified colour (see note 3).

[YELLOW] The default colour is green. [GREEN] [BLUE] [VIOLET] [WHITE]

ALL (colours as above) Displays the mesh for all the geometric parts in the specified colour (see note 3). The default colour is green.

CURRENT (colours as above) Displays the mesh for the currently displayed geometric parts in the specified colour The default is green.

OFF -- Turns off the display of the mesh.

Return Level: VIEW MESH except for ALL or OFF

Notes:

1.

Displaying the mesh for named parts
When displaying the mesh for named parts of the model the name may be prefixed with a `+' or `-' sign to indicate if the part is to be added to, or subtracted from, the current display. If no `+' or `-' sign is prefixed then the display screen is cleared and only the mesh for the named part is displayed. The named part may be any geometric part to which elements are attached.

2.

Superimposing mesh on geometry
If mesh is to be superimposed on the geometry the `+' sign must be used.

Examples:

1.

VIEW MESH Wing

The mesh of the part named `Wing' is displayed.

2.

VIEW MESH +Tail

The mesh for part `Tail' is added to the existing display.

3.

VIEW MESH CURRENT BLUE

The currently displayed mesh is redrawn in blue.

FEMVIEW Command.          

VIEW MESH [Part]

Part Comments

Set name Displays the mesh of the named set.

ALL Displays the mesh for all the model.

Notes:

1.

Displaying the mesh for named sets
When displaying the mesh for named sets of the model the name may be prefixed with a `+' or `-' sign to indicate if the set is to be added to, or subtracted from, the current display. If no `+' or `-' sign is prefixed then the display screen is cleared and only the mesh for the named set is displayed. Where a named set is already displayed then it is only allowable to add or subtract further named sets if these are of the same type (ie. consistently node sets or consistently element sets).

2.

Default Option
If no set is specified the default is the previously specified set.

3.

Viewing a node set
If a node set is specified then the FEMVIEW display routines (which are element based) work differently than when displaying an element set. When displaying a node set, only mesh lines that have both end nodes in the node set will be displayed. Thus if the contents of a node set are such that not all the nodes of an element are contained in the node set, then that element will only be displayed in part. An extreme example is that viewing a node set containing a single node will result in a blank screen, although the presence of the node and its attached elements can be shown by the commands LABEL MESH NODES and LABEL MESH ELEMENTS.

Certain VIEW commands are not supported with node sets. These are VIEW SECTION, VIEW FACES, VIEW DEVELOP, VIEW EDGES, VIEW OPTIONS EDGES OUTLINE and VIEW OPTIONS SHRINK.

4.

Order of drawing
Elements are drawn in the order they are stored in the database and if the model is three dimensional and colour fill is used they may appear to overwrite each other. If this is felt to be misleading then VIEW HIDDEN should be selected.

5.

Shrinking the elements
If VIEW OPTIONS SHRINK is selected the elements will be reduced in size about their centroids.

6.

Removing internal mesh lines
If VIEW OPTIONS EDGES OUTLINE is selected then mesh lines with a connectivity of greater than 1 will not be drawn.

Examples:

1.

VIEW MESH Top

The mesh of the set named `Top' is displayed.

2.

VIEW MESH +Base

The mesh for set `Base' is added to the existing display.
