This option defines uniform loads acting on planar finite elements of a structure. Open the Uniform Planar Load dialog by clicking 
in the Load Definition dialog.
This type of load acts on planar elements. It can also be distributed on bars, if it is applied to a cladding. If so, the load is distributed according to the trapezoidal and triangular method only.
You can define uniform loads applied to the planar finite elements of a structure and acting in the X,Y, or Z direction. Specify the load value in the appropriate field.
You can also define a load in the global coordinate or local coordinate system of an object. You must decide if the load is projected (applies only to definitions in the global coordinate system). When Projected load option is selected, the load is defined in such a way that it corresponds to a surface projected on a plane that is normal to the load direction (separately for each load component).
Planar loads are normally applied to the surface of an entire panel. To facilitate a load definition for curved panels (such as, a cylinder created using the Extrude option), you can select a certain set of finite elements (geometrical limits) for this type of load.
The Geometrical limits button is accompanied by a selection option at the bottom of the dialog:
- When the selection option is cleared, the Geometrical limits button is not available and no geometrical limits are influencing the load.
- When the selection option is selected, the Geometrical limits button becomes available, which lets you define geometrical limits for the load.
