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).
Display the deformed shape of the model.
Deformation Scale Factor
Magnify or reduce the size of the displacement graphically displayed in the model window.
Select the type of display for displacement.
Nodal Deform : Display the deformed shape only with nodal displacements.
Real Deform : In addition to the nodal displacements, for beam elements, it also calculates and displays detailed deformations along the length direction within the segment between the end nodes.
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.
The deformation of the structure is graphically represented relative to the minimum nodal displacement, which is set to "0"
It quantifies the crack coefficient at each nodal point and displays it as a numerical value.
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.

Set Orientation : Display orientation of numerical values.
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.

Free Edge : Draw only the outline of the edges that are not in contact with other solid elements.
Ani. Option Show of Cutting Plane is not supported in Hydration Heat Analysis.
IsoSurface searches and displays the planes of equal stresses resulting from Heat of Hydration analysis within the solid elements.
When you click the button, the detailed settings dialog box for defining the contour plot of stresses generated by thermal analysis will be displayed as follows:
Define the method of specifying the stresses to which the planes are subjected.

Outline (highlight) the solid element model using the following options to clearly view the stress distribution on the planes of equal stresses. The color of the outline is determined from the Color of Display Option or Free Face/Edge of Element under the Print Color Tab.
Draw the outline of all the faces that are not in contact with other solid elements.
Draw only the outline of the edges that are not in contact with other solid elements.
IsoSurface may be used in conjunction with the Animate Option. If one IsoSurface value is entered, the planes of equal stresses are animated within the range of the stress value and the maximum stress value. If two or more stress values are entered, the range of animation starts from the stress level that is lowest of all the values to the maximum value.
