2D visualization functions¶
The functions for visualizing the 2D calculation results are explained.
Use [2D Post-processing Window] for 2D visualization of simulation results as explained below.
[Open New 2D Post-processing Window]¶
Either of the following actions opens a new [2D Post-processing Window].
Menu bar: [Calculation Results] (R) –> [Open New 2D Post-processing Window]
Operation Toolbar: 
The new [2D Post-processing Window] (Figure 386) will open.
Figure 386 [2D Post-processing Window]¶
[Object Browser]¶
Figure 387 shows an example of the [Object Browser] of [2D Post-processing Window].
Figure 387 The [Object Browser] of the [2D Post-processing Window]¶
Settings on the elements shown in the [Object Browser] of [2D Post-processing Window] can be edited mainly from [Draw] menu and [Measured Data] menu. For operations on [Axes] and [Distance Measures], refer to [Axes] and [Distance Measures] respectively.
Note
In iRIC 4.1 and later, the input grid can be displayed in the [2D Post-processing Window]. The input grid display settings are the same as in the preprocessor. See Display Settings for more details.
[Attribute Browser]¶
You can use [Attribute Browser] to see the values of attributes defined at grid nodes.
Figure 388 shows an example of [Attribute Browser].
You can open [Attribute Browser] with the following operations:
Menu bar: [View] (V) -> [Attribute Browser] (A)
Right-clicking menu: Select [Scalar (node)] etc. in [Object Browser], and select [Show Attribute Browser] from right-clicking menu.
While [Attribute Browser] is shown, you can do the following operations using mouse:
When no point is selected, you can see the values of attributes defined at the grid node, by moving the mouse cursor. The attribute values defined at the point nearest to the mouse cursor is shown continuously. The grid node which is selected to show attributes is highlighted with a big black square.
If you left-click on grid node when values are shown in [Attribute Browser], the grid node is selected, and values at that point is shown, until you select another point or clear selection. When you left-click on another grid node, the new node is selected.
If you left-click on point which is outside or the region where calculation result is defined, selection is cleared.

When you click on [Region Setting] button, [Region Setting] dialog (Figure 397 or Figure 398) will open.
When you click on [Color Bar Setting] button, [Color Legend Setting] dialog (Figure 399) will open.
Please refer to [Color Setting] about the dialog that is shown when you select [Custom] as [Colormap] and click on [Setting] button.
Figure 400 shows an example of displayed contours for each [Display Setting] setting.
With iRIC 3.0, it is now possible to visualize contours for multiple calculation results at the same time. To visualize multiple contours, please check on the check boxes for multiple items in the object browser.

[Contour (edgeI)], [Contour (edgeJ)]¶
Description: Sets the contour settings for calculation Results defined at i-direction edges and j-direction edges.
From the values defined at grid edges, values at grid nodes are calculated by interpolation, and contour is drawn with values at grid nodes.
The function to edit setting of contours is the same to the contour function for grid nodes. Refer to [Contour (nodes)] (C) for detail.
[Arrow] (A)¶
Description: Sets the [Arrow] display.
When you select [Arrow], the [Arrow Setting] dialog (Figure 401 or Figure 402) will open. Set it and click on [OK]. Figure 405 shows an example of the [Arrow] display.
