Printing a contour plot at the end of each step

The following example script demonstrates how to produce and print a contour plot at the last frame of every step within an output database file. The example sets the appropriate contour limits so that all plots can be viewed within a fixed range.

Use the following command to retrieve the example script: 

abaqus fetch job=viewerPrintContours

The script does the following:

  • Defines the contour limits function.

  • Determines the final frame of every step within an output database file.

  • Produces a contour plot at the final frame of every step.

  • Prints the contour plot to a file.

Print a set of contour plots to .png files.
