Time step animation
You can use the report steps available for the property. To view report steps, select to
step by - Displayed You can use the report steps from another property. Select
to step by - Selection You can specify the report steps. Select to step by - User Interval
Set current date and time of display.
3D results from simulation are accessible from the Results pane. To display simulation results, you must select a property and a simulation case. If the property is time dependant, the time player is used to animate the display through time.
In the folder Composite results, properties are stored as ternary properties (saturation), vectors, and tensors. The Static folder stores static input data to the simulators (INIT file). The Dynamic folder contains data from the restart file and these typically change with time.
3D Viewing
1D filters
Right-click the property and select
Create 1D filter...
A 1D filter can be used to limit the range of cells displayed for any property.
Use the property from relevant case.
Select the relevant report step.
Right-click on a property in the Simulation grid results folder and select Create 1D filter. In the dialog that opens, you can drag the sliders to select the range of values you want to filter out. Here, you specify which simulation case the property is referring to and also which report step the filter should be applied to. The filter is stored on the Input pane under the Filters folder, and can be turned on and off.
The time player speed can be changed from the Project settings menu.
The simulation grid results properties can be converted to grid properties, and will be stored in the Properties folder on the Models pane.
This can be done to access more property operations, for example, map creation.
3D Viewing
I, J, K layer filter
You can view all cells with the same I, J, or K index by pressing the filter symbol in the function bar.
The filter tools are available in the function bar when any of the property modeling processes are active.

User filters
You can make filters interactively from function and histogram windows.
In a histogram window, you can drag a section along the x-axis to specify the filter. The new filter will appear on the Input pane and can be applied to other properties. In the illustration above, the histogram window is used to make a filter for high values of porosity. This filter is applied in a 3D window to show oil saturation in high porosity cells. It is also possible to create a filter from a function window. For example, a cloud of data points can be selected from a cross-plot of two properties.

Select Saturation from the
Simulation grid results
(Composite results sub-folder). Activate Show/hide auto legend from the toolbar.
Right-click on the Intersections folder on the Models pane and select
Insert general intersection. An intersection plane is added to the
folder.
When the general intersection is displayed in the 3D window, the intersection toolbar appears.
Click the Toggle visualisation on plane tool button to enable visualization on the intersection plane. Once this tool is activated, subjects with blue check boxes can be displayed on the intersection. Use the Manipulate plane tool from the function bar to drag the plane.
Intersection window
The intersection plane can be turned into an intersection window.
Right-click the general intersection and select Create intersection
window to display your general intersection in an intersection window.
Select the check box in front of the subjects to put them into view. If you drag the general intersection in the 3D window, the intersection window is automatically updated.
Exercises – Results viewing
In the previous exercise, you initialized the 3D grid. This exercise will show you how to display 3D properties.
Exercise Workflow
• View 3D simulation data • Use filters
• Use of general intersection planes • The multi-value probe
Exercise Data
For this exercise, continue to use the project you used in the previous exercise.
3D viewing
Your simple grid is now initialized and the initial properties are stored in the sub-folders of Simulation grid results on the Results pane. You can view any of the initial properties, such as saturation or pressure in a 3D window. The exercises demonstrate how to apply different filters for a better view.
Exercise steps
1. Open a new 3D window.
2. Go to the Cases pane and select the relevant case. 3. Go to the Results pane, and expand the Simulation grid
results folder. Then, expand the Dynamic sub-folder. Select
to display Water saturation (SWAT).
4. Click the Show/hide grid lines button in the function bar to display the grid lines. If the icon is not on the function bar, activate the Define simulation case process on the
Processes pane.
5. Click the Show/hide axis button in the menu bar to display the coordinate axis.
6. Click the Show/hide auto legend button in the menu bar to add the legend to view.
7. To get a better view, you can apply filters. Right-click on Water
saturation, and select Create 1D filter.
8. In the dialog, use the slider to select a minimum water saturation of 0.35. Click Apply, and observe the change in the
3D window. Click OK to close the dialog.
9. Go to the Input pane, open the Filters folder and turn off the filter you just made.
Using I, J, and K filters in a 3D window
There is a wide range of available filters you can use when you are viewing data in 3D.
Exercise steps
1. Continue to work with the 3D window displaying the water saturation.
2. To make the I, J, and K filters available, activate the Define
simulation case process from the Processes pane.
3. Click the Display the cells with same K button to view one K-layer at a time.
4. You can use the Step property forward/backward buttons / to go to another K-layer.
5. Click once more to cancel the K-layer filter.
6. Click the Toggle simbox view button to change to a view that flattens the model.
Making filters using a Histogram window
You can make a filter based on data displayed in a histogram or a function window. The filter can be applied to data displayed in a 2D or 3D window.
Exercise steps
1. Open a histogram window, and display the initial pressure 2. Click the Select using 1D range on x-axis button in the
function bar.
3. Left-click in the histogram window and drag to select the values that should define the filter. Select only the largest pressure values to create a filter that exclusively displays the cells with high pressure.
4. Go back to the 3D window that displays the water saturation. 5. Go to the Input pane and expand the folder Filter folder >
User.
6. Select the Pressure filter, and observe the effect in the 3D window.
View data on an intersection plane
You can insert a general intersection into the model and select to view data on it. The plane can be moved and tilted.
Exercise steps
1. Use the 3D window displaying the water saturation, but turn off all filters.
2. Right-click the Intersections folder under your 3D grid (Simple) and select Insert general intersection.
3. Click the Clip in front of plane button in the General
intersection player toolbar at the bottom of the user
interface.
4. To view data on the plane, click the Toggle visualization on
plane button on the intersection plane toolbar.
5. Items that you can display on the plane now have a blue box or a radio button. Select the box in front of Water saturation to view the saturation on the plane.
6. Click the Manipulate plane button in the function bar to move the plane to a different position.
7. Right-click the General intersection on the Models pane and select Create intersection window.
8. Select to display the water saturation in the intersection window.
9. Select to tile the intersection window and the 3D window by selecting Tile vertical from the Windows menu.
10. Move the intersection plane in the 3D window and notice how the intersection window is updated simultaneously.
Optional Exercise - The multi-value probe
Sometimes it is useful to be able to view several property values in the same grid cell. The Multi-value probe gives you a tabular view of the grid properties.
Exercise steps
1. Return to your 3D window that displays the water saturation and select to view the pressure.
2. Now you have an access to the Multi-value probe mode button in the function bar.
3. In the dialog that opens, add four rows by clicking the Append
item in the table button .
4. Use the blue arrow in front of each row to drop the property into the dialog. Start with porosity from the fine grid.
5. In order to use the grid properties from the simulation results, simulation case need to be provided (see Input part of the dialog). Drop in the Simple case from the Cases pane as shown in the picture below. In the Results part of the dialog, drop in Porosity (PORO) from the Static sub-folder of the
Simulation grid results. Then, from the Dynamic sub-folder
drop in Water saturation (SWAT) and Pressure
(PRESSURE). Note: these properties were taken from the first
time step.
6. Left-click on any cell in the 3D window and observe how the table is updated to show the property values in that cell. Note that you can compare the property values between different grids by using this tool.
