Contour fill, cuts and limits

Contour fill

Menu: View results->Contour fill

Please select View results->Contour fill->Pressure through the menu bar, or clicking on or using the Window->View results... window.

If not all sets show the contour fill like the picture above, remember to select Body Boundaries mesh style for all the sets.

This option allows the visualization of result using a color map, in which a scalar variable or a component of a vector varies between two defined values. GiD can use as many colors as permitted by the graphical capabilities of the computer The number of colors can be set through Utilities->Preferences - Postprocess->Contour fill and lines
By number of colors.
A menu of the available results to be represented will be shown, and the one that is chosen will be displayed using the current step selected.
In the model the pressure has been calculated. We can visualize the result for each step in a contour fill.
You can choose the step that you want to view through the View results window or clicking on the icon

Select the analysis named RANSOL and its step 103.0

Several configuration options can be set via the preferences window .
You can change the color scale in order to get a more comfortable view. You can select several predefined color maps The default scale is rainbow, which is a rainbow color map starting from blue (minimum) through green and yellow, to red (maximum).

Select Color map: Inverse rainbow

You can also define your own scale.

Select Color map: User defined... then the button 'More color options' could be picked to open a colors window. In this window you can change the number of different colors used in the scale. If you need more accuracy you can increase this number, or decrease it for a higher contrast.
Change the number of colors to 10
Click on Apply button
Click on Close button

Cuts
In order to view the inner zone we will do several cuts along the model.

Menu: Geometry->Cut plane

In order to make it easier first we will change the plane visualization.

Please select View->Rotate->Plane XY(Original) through the menu bar, Rotate->Plane XY(Original) through the mouse menu or clicking on and . Now you have a top view of the model.

Cuts are done to both the volume sets and the surface sets resulting in triangle meshes and line meshes. In this case we only want to cut the volume meshes, so please switch off all surface meshes
Select Geometry->Cut plane->Succession through the menu bar or clicking on and then

With the succession option you specify an axis that will be used to create cut planes orthogonal to this axis. The number of planes is also asked for.

Draw a line through the X axis in the middle of the model and ask for 7 cuts. You should obtain 7 parallel planes to Y axis.

Note: after clicking the first point, pressing the Alt key while moving the mouse the dynamic line will be screen-axis aligned or at 45 degrees.

Now open the display style window (Window->View style) to switch off all meshes except the created Cuts. You can see that several layers have appeared with a prefix like Cut indicating which mesh or set has been cut. These names can always be changed by selecting the mesh and pressing F2 or right-click and rename option.
Select all the layers except the cuts and change their style to Boundaries . You can rotate the model in order to see the contour fill result on the cut planes.
In the same window select all the Cuts and click on Delete button in order to delete them.
Select Body Bound as mesh style to visualize the contour fill of pressure again.
In the preferences window , select Postprocess->Contour fill and lines and press the Default values button in order to restore the default options.

Define limits
You can set the minimum and maximum limit values for the contour fill. In our case we only want to see the positive values. In order to do this we will set the minimum value to 0.0 .

Click on the icon of the toolbar, and an entry will ask you for the minimum value that Contour Fill should use. Change the value to 0.0 and press return to accept the value and close.

Outliers will be drawn in the color defined in the Out minimum color option of the preferences window . In order to filter out the negative values we will change this color to transparent.

Select Out minimum color: Transparent and press Apply.
