Study Results for 2D-DIC¶
If you have just run a DIC analysis (as described in Make and Run 2D-DIC Input File), you will see the DIC input file under the DIC node in the Workspace Tree.
If you have run the DIC analysis in a previous session, you can load the input file by right-clicking the “DIC” node in the Workspace Tree and choose “Load Input File...”. The input file will then appear as the image above.
Right-click the on the input file in the Workspace Tree, and choose “Results View (image)” in the context menu.
The Results View (Image) will appear as shown below. The results viewer is linked to the specified input file. It is possible to open multiple result viewers for different input files.
In the listbox to the right in the Results View (Image) , all the images in the DIC analysis are listed. You can decide which image to study by clicking in this list. By scrolling through the images in the list, you will see how the mesh has evolved from image to image.
The main features in the post-processing of the DIC analysis is:
- Vizualize field maps
- Plot data in figures
- Export data to text files
In the following, these three features will be discussed.
Vizualize field maps¶
To vizualize field maps, open the Field Map Tool (from menubar: Tools -> Field Maps).
The Field Map Tool contains a tree structure of all data that are available as field maps. For a description of the different data types, see Data Types
Right-click on the data type you want to plot as field map, and click “Set As Field Map”:
You will now see the specific field map plotted on-top of the image in the Image Panel.
An example of a 1. principal strain field plotted ontop of a unisxial tension specimen is shown below.
A colorbar is shown if you click “Show Colorbar” in the Field Map Tool.
Plot data in figures¶
To plot data in figures, open the Graph Tool (from menubar: Tools -> Graph).
The Graph Tool contains a tree structure of all data that are available for graph plotting. For a description of the different data types, see Data Types
You need to specify which data types are going to be set to the horizontal- (X-) axis of the figure and which data type which are going to be set to the vertical (Y-) axis of the figure. Right click on the data type and select which axis you want to set the data type.
When you have added a data type to the X-axis and the Y-axis, you can click “Add Data to Graph”. The new data series will then be generated and added to the current Figure. If no Figure is present, a new will be opened.
Note
For some Data Types you need to select either “Elements”, “Nodes” or “Vectors”. This can be done using the Mesh Select Tool.
Export data to text files¶
To export data to text files, open the File Write Tool (from menubar: Tools -> File Write).
The File Write Tool contains a tree structure of all data that are available for text file export. For a description of the different data types, see Data Types
The File Write Tool works in a very similar manner as the Graph Tool described above. Right-click on the data type you want to add to the text file, and click “Add Data to List”. The data type is added to the list below. When you have added all the data you want to be written to the text file, click “Write data to text file...”
Note
For some Data Types you need to select either “Elements”, “Nodes” or “Vectors”. This can be done using the Mesh Select Tool.
Generating Video¶
Videos of the image series with various field maps may be generated using the Video Generation Tool (from menubar: Tools -> Video Generation). (See Video Generation Tool for details on how a video can be generated)
