0-Check.jpg Type of Display

 

Define the type of display as follows:

 

Contour

Display the stresses of beam elements in contour.

0-Point.jpg

 

00-Contour_Details.jpg

Ranges: Define the contour ranges.

 

0-Customize_Range....jpg: Assign the color distribution range of contour. Using the function, specific colors for specific ranges can be assigned.

 

Note
Contour Range Max/Min values can be larger than the max/min output values.  

If the Contour Range values exceed the output values, they are entered at Rank 0 and Rank 11.

 

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

 

Colors: Assign or control the colors of the contour.

 

Color Table: Assign the type of Colors.

 

0-Customize_Color_Table....jpg: 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.

 

Extrude
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).  

Deform

Display the deformed shape of the model.

0-Point.jpg

 

00-Deformation_Details.jpg

Deformation Scale Factor
Magnify or reduce the size of the displacement graphically displayed in the model window.
 

Deformation Type
Select the type of display for displacement.

 

Nodal Deform: Display the deformed shape only with nodal displacements.

 

Real Displacement (Auto-Scale off): The true deformation of the structure is graphically represented without magnifying or reducing it. This option is typically used for geometric nonlinear analysis reflecting large displacement.

Relative Displacement: The deformation of the structure is graphically

 

represented relative to the minimum nodal displacement, which is set to 0.

Values

Display the displacements of solid elements resulting from Heat of Hydration analysis in numerical values.
The font and color of the numbers can be controlled in 0-Display_Option.jpg Display Option

0-Point.jpg

 

00-Value_Output_Details.jpg

Decimal Points: Assign decimal points for the displayed numbers.

Exp.
: Express as exponential.
 

Min & Max: Display the maximum and 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 the nodal displacements of solid elements relative to the selected maximum or minimum value.
 

Set Orientation: Display orientation of numerical values.

 

Note
The default Decimal Points can be controlled in "Preferences".
Set Orientation = 0 horizontally displays the numerical values to the right of nodes or elements.
The orientation angle represents the counter-clockwise direction, which may be used to enhance the readability of the numbers.

Legend

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

0-Point.jpg

 

00-Legend_Details.jpg

Legend Position: Position of the legend in the display window

Rank Value Type: Specify a type of values in the Legend and the number of decimal points.

Undeformed

Overlap the undeformed and deformed shapes of the model.
The display method of the undeformed shape can be controlled in  0-Display_Option.jpg Display Option.

Animate

Dynamically simulate the transition process.

 

Click 0-Apply.jpg then click 0-Record.jpg Record to the right of the Animation control board at the bottom of the working window.

The state of deformed model with the display of loading time can be checked by time history analysis steps.

 

Animate Contour: Option to change the color of the contour representing the transition according to the magnitudes of variation

Repeat Half/Full Cycle
: Select the repetition cycle for the dynamic representation of the transition.
