Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| SID | Load set identification
number. No default (Integer > 0) |
|
| EID | Element identification
number. No default (Integer > 0) |
|
| PA | Surface traction at grid
point GA. No default (Real) |
|
| PB | Surface traction at grid
point GB. No default (Real) |
|
| GA, GB | Identification numbers of
two adjacent corner grid points on the element side. No default (Integer > 0) |
|
| CID | Coordinate system
identification number. A CID of zero or blank
identifies the basic coordinate system. Default = 0 (Integer ≥ 0, or blank) |
|
| N1, N2, N3 | Components of a vector
measured in the coordinate system specified by
CID. The vector defines the direction of the
load and is normalized internally such that it does not contribute
to the magnitude of the load. If N1,
N2 and N3 are all blank,
the in-plane inward normal is used as default. Default = In-plane inward normal (Real or all blank) |
Comments
- The surface traction is assumed to
vary linearly along the element side between GA and
GB.

- The surface traction is input as force per unit area.
