Cohesive Element Deletion?

Hey,
Can't get my cohesive elements to "delete" once they fail:

Working my first Abaqus simulation....a simple 2D Aluminum cube loaded in tension with a single row of cohesive elements sandwiched in the middle. I built the model as 3 separate meshed parts and used tie constraints to put the three layers together. My tension run is "successful"...i.e. the expected stress strain curve is correct. The cohesive elements begin to degrade and then fail exactly as I specify. However, once the stress in my model falls to zero (failure), the cohesive elements remain (visually) in my model. In the mesh module, under mesh->element type, I toggled on "element deletion->yes". Should I be able to "see" (in the visualizer) my model fail along the row of cohesive elements?...and if so how? I plan to build more complicated models and would like to have some pictures of my models "failing" for presentation.

Much appreciated!

I'm not sure about cohesive elements, but with solid elements, you have to request the element STATUS flag as output. You can then create a display group in Viewer that only shows the active elements with STATUS=1.
