PLOAD
Bulk Data Entry Defines a static pressure load on a triangular or quadrilateral element. It can also be used to define the EXCITEID field (Amplitude "A") of dynamic loads in RLOAD1, RLOAD2, TLOAD1 and TLOAD2 Bulk Data Entries.

Comments
- The grid points define
either a triangular or a quadrilateral element to which a pressure is applied. If
G4 is zero or blank, the element is triangular.
In the case of a triangular element, the assumed direction of the pressure is computed according to the right-hand rule using the sequence of grid points G1, G2, and G3.
- The total load on the element, AP, is divided into three equal parts and applied to the grid points as concentrated loads. A minus sign in field 3 reverses the direction of the load.
- In the case of a quadrilateral element, the grid points G1, G2, G3, and G4 should form a consecutive sequence around the perimeter. The right-hand rule is applied to find the assumed direction of the pressure.
