Add a Point Load to points for concentrated forces or moments at points. The loads are defined in the given coordinate system. From the Coordinate system list select from:

This setting is used in conjunction with Shell Local System. When the load is applied to an edge which is shared between boundaries, the coordinate system can be ambiguous. Select the boundary which should define the edge system. The default is Use face with lowest number.

Select a surface — Top Surface, Midsurface, or Bottom Surface. The default is that the load is applied at the midsurface. The effect of using another surface than the midsurface is that for a tangential load, the distance from the midsurface is used to compute an additional equivalent moment load.

To place the load at another distance from the midsurface, select the Offset check box, and enter a value for the offset, zoffset.

If the material model is Section Stiffness, there may physically not be a well-defined top and bottom surface. If the load is applied at such a surface, the thickness value used to compute the load is taken from the settings in the Thickness and Offset node.

If a selected point is connected to boundaries having different thicknesses, then the result of specifying Top Surface or Bottom Surface is not well defined.

Enter values or expressions for the components (x, y, z) of the point load FP.

Enter values or expressions for the components (x, y, z) of the point moment MP.

If you are performing a linear buckling analysis with a combination of live and dead loads, select the Treat as dead load check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
