Surface Results Adjustments

A surface results adjustment describes a zone in the model whose graphical results are not represented by the actual diagrams, but as mean values. A user-defined adjustment zone allows you to evaluate the smoothed surface internal forces and moments. The function corresponds to the "Average Region" implemented in RFEM 5.

01 Dialog Box "New Surface Results Adjustment"

Parameters

The following options are available for the 'Form' of the zone:

• Rectangle
• Circle
• Ellipse

Enter the 'Dimensions' zone by means of the shape-specific parameters. They are illustrated in the dialog graphic. If the zone needs to be rotated, you can specify the value of the 'Angular rotation'.

Center Position

Specify the center of the adjustment zone. You can enter the coordinates or define them graphically using the button.

Adjustment Type

In this dialog section, you can define the surface internal forces and moments to be taken into account for smoothing. You can specify separate specifications for 'Direction u' (first direction) and 'Direction v' (second direction, orthogonal to u direction). The list (see the image New Surface Results Adjustment) provides the following options:

• Averaging of m_y, m_xy, v_y, n_y, n_xy: Default setting for basic internal forces in surface direction y
• Averaging m_x, m_xy, v_x, n_x, n_xy: Default setting for basic internal forces in surface direction x
• User-defined: The results of selected types of internal forces are averaged. Use the button to define the relevant surface internal forces (see the image Selecting Types of Internal Forces.
• Zero: The results within the zone are set to zero. Use the button to define the type(s) of internal forces (see the image Selecting Types of Internal Forces).
• None: The surface internal forces are not averaged, but displayed as usual.

Projection in Direction

This dialog section controls the relation of the defined zone to the surfaces. Generally, the projection is perpendicular to the surfaces. However, global projection directions or any projection vectors are also possible.

06 Selecting Projection Direction

The 'Vector' can be defined graphically by clicking two points with the button.
