Menu: View results→Graphsresults->Graphs
From this menu several graphs types can be created, we will try some of them. Graphs are supported for results defined over nodes because they represent a continuous field (gauss-element results represent a discontinous discontinuous field)
Graphs are organized into graph sets in order to ease the management. Each set shares the same units for each axis.
When a graph is created is placed in the current graphset if the units are the same, otherwise a new graphset is created.
In order to work with graphs we will use the 'graphs window'.
...
- Select View results->Graphs->Point evolution->Velocity->|Velocity| . You can also click on the graphs icon and select the point evolution option:
- Write 20,0,4 in the command line in order to specify the point.
- Affter After pressing the <Esc> key, or the middle mouse button, the graph will be shown in a separate window:
The graph is created in the graphset-1. We will create another graph in the same graph set.
The Line graph displays a graph along the line conectig connecting two selected nodes of surfaces or volumes, or any arbitrary points on any projectable surface and in any position.
- Switch all surface meshes off, and let only the three volume meshes on: volumes, cil, wake.
- Create this graph from the 'Create' tab of the Graphs window
Press the Apply button to select the two points of the line:
...
You can create this graph also from the results icon bar:
Now both graphs are showed in the same graph set:
We will rename the graph set.
...
- Go to Create tab and select Point evolution int View option.
- In Y Axis list double click Pressure.
- Press Apply to select the point and write 50,0,0 in the command line in order to specify the coordinates of a new point (<Ctrl>-a to swap to select an existent node by its id)
- Press <Esc> to finish the selection of points and create the graph:
We can manage graphs and graphs sets in the Options panel. Depending if we are selecting a graph set or a graph in the tree we will see different options in the tab.
- Go to the Options panel, select the 'Velocity (m/s) evolution at ( 20, 0, 4)' graph and delete it pressing the button with the red cross.
- A confirmation window appears. Click Yes.
- Please notice that the current graph set have been changed to 'Velocity'. Now the Plot graph panel will show only one graph:
The graph size is readapted. We can will change several style options of a graph.
- ouble Double click in any point of the graph and we will access to the Options tab.
- Set Style: Line
- Set to red the Color option. You can do it writing #ff0000 or selecting the red clicking on the right color window
- Set to 4.0 the Line width
- Click on Apply button
...
- Select Velocity branch. The options will change.
- For instance mark Logarithmic scale option in X axis.
- Click on Apply button
We can export the graph information in order to open it later with GiD or other third party programs.
...
- Select View results->Graphs->Clear in order to delete all the graphs, or choose the clear graphs option from the graphs icon menu:
