Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| SID | Load
set identification number. SID
must be unique from all NLOAD1
entries. No default (Integer > 0) |
|
| S | Scale factor. No default (Real) |
|
| Si | Scale factors. No default (Real) |
|
| Li | Load
set identification numbers of NLOAD1. Each
Li must be unique from any other Li on the
same entry. No default (Integer > 0) |
Comments
- Dynamic load sets must be selected in the I/O Options or Subcase Information sections with NLOAD=SID.
- The
load vector being defined by this entry is given
by:
(1) - An NLOAD entry may not reference a set identification number defined by another NLOAD entry.
- This card is represented as a load collector in HyperMesh.
