Load set identification number. (Integer > 0) |

P |
Pressure. (Real ¹ 0) |

G1,...G4 |
Grid point identification numbers. (Integer > 0; G4 may be 0) |
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.
