Influence Surfaces - Displacements


  • Check the influence surface of a nodal displacement.



From the main menu, select [Results] tab > [Type : Analysis result] > [Moving Load] group > [Influ.Surfaces] > [Displacements]

Displacements dialog box


Line/Surface Lanes

Select a traffic lane for which the influence surface analysis results are to be checked.

Key Node : Enter a node number, or click the entry field and the desired node in the working window.



Select a desired displacement component.

DX : Displacement component in GCS X-direction

DY : Displacement component in GCS Y-direction

DZ : Displacement component in GCS Z-direction

RX : Rotational component about GCS X-axis

RY : Rotational component about GCS Y-axis

RZ : Rotational component about GCS Z-axis


Type of Display

Assign the type of display.

1. Contour

1. Contour

Display the reaction influence surface in contour.


Ranges : Define the contour ranges.

Customize Range... : Assign the color distribution range of contour. Using the function, specific colors for specific ranges can be assigned.

Number of Colors : Assign the number of colors to be included in the contour (select among 6, 12, 18, 24 colors)

NOTE.png We have changed the output value to allow the value outside of the maximum and minimum values to be specified as Contour Range Max/Min. If it is within the Min/Max range, it will be treated the same as before, and if it is beyond the range, Min/Max has been modified to be entered in Rank 0 and Rank 11.

Colors : Assign or control the colors of the contour.

Color Table : Assign the type of Colors.

Customize Color Table... : Control the colors by zones in the contour.

Reverse Contour : Check on to reverse the sequence of color variation in the contour.

Contour Line : Assign the boundary line color of the contour

Element Edge : Assign the color of element edges while displaying the contour

Contour Options : Specify options for contour representation

Contour Fill

Gradient Fill : Display color gradient (shading) in the contour.

Draw Contour Lines : Display color boundaries in the contour.

Draw Contour Line Only

Display only the colored boundaries of the contour.

Mono line : Display the boundaries of the contour in a mono color.

Contour Annotation

Legend or annotation signifying the ranges of the contour is displayed.

Spacing : Specify the spacing of the legend or annotation.

Coarse Contour(faster) (for large plate or solid model)

Represent a simplified contour for a large model using plate or solid elements in order to reduce the time required to represent a complete contour.


Where plate elements or solid elements along a cutting plane are represented in contour, a three dimensional contour is created. The positive direction of the analysis results is oriented in the z-axis direction of the local element coordinate system.
The option is not concurrently applicable with the Deformed Shape option. Similarly, the option cannot be concurrently applied to the cases where the Hidden option is used to display plate element thicknesses or the Both option is used to represent Top & Bottom member forces (stresses).


2. Legend

2. Legend

Display various references related to analysis results to the right or left of the working window.


Legend Position : Position of the legend in the display window

Rank Value Type : Specify the output type and number of decimal places for the Legend value


3. 3D Contour

3. 3D Contour

Display the reaction influence surface in a 3-dimensional contour.


Scale Factor : Enter the drawing scale factor for the 3-D contour.

Draw vertical lines : Display vertical lines inside the 3-D contour.


4. Values

4. Values

Display the reaction influence surface in numerical values.
The font and color of the numbers can be controlled in Display Option.


Decimal Points : Assign decimal points for the displayed numbers.

Exp. : Express as exponentials.

Min & Max : Display the maximum, minimum values.

Abs Max : Display the absolute maximum value.

Max : Display only the maximum value.

Min : Display only the minimum value.

Limit Scale(%) : Set the screen display limit for reaction influence surface values relative to the selected maximum or minimum value.

Set Orientation : Display orientation of numerical values.

NOTE.png The default Decimal Points can be controlled in "Preferences".

Set Orientation = 0 horizontally displays the numerical values to the right of nodes or elements. Orientation is applied at a counterclockwise angle. Entering an appropriate angle can greatly improve readability when outputting a numerical value.
