PLOAD2
Bulk Data Entry Defines a uniform static pressure load applied to two-dimensional elements, or a SET of such elements.
Only QUAD4 or TRIA3 elements may have a pressure load applied to them via this entry. It can also be used to define the EXCITEID field (Amplitude "A") of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 Bulk Data Entries.

Definitions
| Field | Contents | SI Unit Example |
|---|---|---|
| SID | Load set identification
number. (Integer > 0) |
|
| P | Pressure value. (Real ≠ 0) |
|
| EID/ELSETID, EID1, EID2 | Element identification
number, or if the ELSET continuation line is
specified, an identification of a SET of
elements. At least one positive
EID/ELSETID must be
present on each PLOAD2 entry.
Where, <String> specifies a user-defined string label for the set. 5 |
|
| ELSET | Flag which indicates that the EID/ELSETID field is identified as a SET of elements at which the loads are applied. |
Comments
- If the alternate form is used, all elements EID1 through EID2 must be two-dimensional.
- The direction of the pressure is computed according to the right-hand rule using the grid point sequence specified on the element entry. Refer to the PLOAD entry.
- All elements referenced must exist.
- Continuations are not allowed.
- String based labels allow for easier visual identification of sets, including when being referenced by other cards. For more details, refer to String Label Based Input File in the Bulk Data Input File.
- This card is represented as a pressure load in HyperMesh.
