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.
