Print Contour Plots

viewerPrintContours.py from Printing a contour plot at the end of each step.

Print a set of contour plots to .png files.

Run the following command before running this script:

abaqus fetch job=viewer_tutorial

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.

# Create a viewport for this example.

myViewport = session.Viewport(name="Print contour plot after each step", origin=(10, 10), width=150, height=100)

# Open the output database and associate it with the viewport.
# Then set the plot state to CONTOURS_ON_DEF

    myOdb = visualization.openOdb(path="viewer_tutorial.odb")

    print("Error:", e)

# For each step, obtain the following:

#     2) The number of frames in the step.
#     3) The increment number of the last frame in the step.
