Why is there no stress data with a Hyperelastic material under displacement?

Hi:

 

I used Treloar's simple tension, planar tension, and equialbiaxial tension data to run a model with an Ogden material model.

 

Under applied displacement, I get good behavior. The strain and displacement data are available.

 

However, there is no stress data in the results.

 

Although the stress result plot shows colors that indicate high and low stress, the values are all 0.0 exactly.

 

How can I get the stress values to appear?

 

Thanks.
