# FE Surface Loads \[FEA]

FE surface loads apply pressure or concentrated loads directly to surface (shell) elements. These loads act on the element face and are automatically converted to equivalent nodal forces during analysis.

## Point Load

Loads applied to a surface element, including uniform pressure, concentrated forces, and concentrated moments.

**Load Case:** The analysis case (load case) to which this surface load belongs.

**Element:** The surface element (FESurface) to which the load is applied.

**System:** The coordinate system for the load direction. Select Global to define the load in global XYZ directions, or Local to define it in the element's local coordinate system.

**Direction:** The direction in which the forces act (e.g., X, Y, or Z of the selected coordinate system). For pressure loads, Z in the local system is normal to the shell surface.

**Uniform Force Magnitude:** The magnitude of the uniform pressure applied over the entire surface element (force per unit area). Positive values act in the positive direction of the selected axis.

**Point Force Magnitude:** The magnitude of a concentrated force applied at the specified local coordinates on the surface element.

**Point Moment Magnitude:** The magnitude of a concentrated moment applied at the specified local coordinates on the surface element.

**X Coord. (in elem. local):** The X coordinate of the point load location in the element's local coordinate system. Used to position concentrated forces and moments on the surface.

**Y Coord. (in elem. local):** The Y coordinate of the point load location in the element's local coordinate system. Used to position concentrated forces and moments on the surface.
