Here's an example of the lines you can add to include the contour plot of SDEG:

```

*OUTPUT, FIELD, VARIABLE=PRESELECT

*ELEMENT OUTPUT, ELSET=, SDV=

```

Replace `` with the name of the element set for which you want to visualize the SDEG contour. `` should be replaced with the specific strain-displacement equivalence gap variable number associated with the cohesive zone model. The variable number depends on the order in which the variables are defined in the cohesive zone model definition.

Make sure to place these lines appropriately in your input file, after the cohesive zone model definition and before the analysis step.

By including these lines, Abaqus will output the values of the specified SDEG variable for the elements in the specified element set. You can then view the contour plot of SDEG in Abaqus CAE by following these steps:

1. Load the results file (.odb) in Abaqus CAE.

2. Go to the "Visualization" module.

3. Select the desired step and frame in the "Field Output" tree on the left.

4. In the "Results" menu, click on "Contours."

5. In the "Contours" dialog box, select the variable corresponding to SDEG from the drop-down list.

6. Adjust the contour settings as needed (e.g., contour range, colors, etc.).

7. Click "Apply" or "OK" to generate the contour plot of SDEG.

Ensure that you replace `` and ``

Good luck

Thank you sir your reply!!

But I have one quick doubt, SDEG we can see for whole model if we insert the cohesive element between two surface.

So, in my code if I use variable=ALL in output field (in my above code), will it be correct?

If you have any file with you where you used the ` (this element set definition), could you please send it.
