CONSTRUCT SCURVE [scurve] BODY CORNERS v1[-v8]

   

This command is used to define a space curve which varies over a body. The user may specify a value at each corner of the body.


scurve = name of the space curve
v1-v8 = value of space curve at each corner of the body

Notes:

1.
Default names
If no name is entered a default name is created, this is SCn where n is a count of defined space curves. The default name can be changed with the CONSTRUCT NAME command.
2.
Interaction with loads
A body space curve will multiply a load at a node, element face centroid or element centroid (depending upon the load type) by the value of the space curve at that point in space.
3.
Interaction with load masks
A body load mask will compress a body space curve so that all of the curve fits within the load mask limits. A global load mask will truncate a body space curve.
4.
Viewing space curves
Body space curves may only be viewed by applying them to a load and using the command LABEL MESH LOADS.
5.
Evaluation of BODY CORNERS space curves
The space curve value for these curve types is evaluated by linear interpolation over the body.
6.
Permitted body topologies
The body load mask can only be applied to six-sided bodies made up of four-sided surfaces with straight sides. The sides of the surfaces can be combined lines.

Examples:

1.
CONSTRUCT SCURVE BODY CORNERS 0 0 0 0 100 100 100 100

This creates a space curve which varies from 0 to 100 in the body local z direction.
