Input the pressure loads on the face or edge of a plate element, plane stress element or solid element. Uniform load and linearly/non-linearly distributed loads can all be defined. The pressure load acts on the target geometric surface in a linearly/non-linearly distributed form per unit area and hence, the units are [Force/Area]. Because it is the force per unit area, it is applied to all selected target surfaces equally. The pressure is differ with the Force because the Force is using unit [N] and the force is loaded as nodal loads at sub-nodes generated at the selected geometric surface.

Because the Pressure load considers the area of the target surface (element surface) and is automatically converted as a nodal load for analysis, the two load conditions do not have a difference in analysis results. The more convenient load, depending on the applied direction, can be selected and used from the concentrated/distributed load option given in Analysis Condition.

The pressure is input in distributed force form for an element face or edge. It can be used on 2D or 3D elements and the input direction can be specified as an arbitrary coordinate axis direction, arbitrary vector direction or normal direction. The direction setting is the same as for [Force]. Uniform load size or linearly/non-linearly distributed load size can all be specified as shown below, and the load change can be defined using a function of coordinate direction/distance. When applying a function, the input value is multiplied by the function value for application as a total load.
