Visualize the data

During a simulation, it is possible to visualize the data as Graphs or in a Sensor table

1 Graphs

The data obtained during a time simulation can be visualized live while the simulation is running. In order to visualize the data, check the box next to the selected field, as shown in the figure below. 

            

This will open a graph in the Graph pane in the lower right corner of the Simulation window. Note that you can plot multiple graphs by checking different boxes. The graph provides differenct funcionalities which are shown and listed below.



  1. Graph area: the data is plot here. If the y-axis is unlocked (see point 6), you can zoom in and out of the graph bu scrolling with the mouse
  2. Graph name: the name contains the sensor (in this example 'Generator') and the output ('Power (electrical)'). You can superimpose a graph onto another one by clicking on its name and dragging it onto the other graph. Note that this is only possible for output with the same units.
  3. x-axis range: clicking this icon opens a dropdown menu where you can adjust the x-axis range of the graph. It is possible to define a custom range by selecting 'custom time'
  4. Display statistics: clicking this button will display the statistics corresponding to this graph: minimum, maximum, mean and standard deviation. By default the statistics are clculated from t = 0, but you can select the starting time in the Analysis parameters.
  5. Close graph: this button closes the corresponding graph
  6. Lock y-axis: if the lock is closed (i.e. default value), the y-axis range is defined automatically so that all the data is visible in the graph. When clicking the icon, the lock is opened and you can define the y-axis range by scrolling with the mouse
  7. Close all graphs: closes all the graphs

2  Sensor table

The Sensor table view can be opened by clicking the icon highlighted in red in the picture below


This will open a window with all the data recorded during the simulation, as shown in the picture below. The left pane of this window allows you to navigate between the different sensors used in the simulation.



3 FFT

It is also possible to plot the FFT of any field during a simulation, by right-clicking the field and selecting Add frequency spectrum graph, as shown in the figure below:



The x-axis in the FFT graph corresponds to the frequency in Hertz, the y-axis is the amplitude of the FFT components divided by the next power of 2 of the number of samples.
