Abaqus version: 2018.hf4

We have requested Stress and Strain data to be written at nodes. It was required to have nodal results to post-process the data easily using Abaqus Python APIs. This we have done using following option in .inp file:

"*Element Output, directions=YES, POSITION=AVERAGED AT NODES"

But, when I want to view the Stress components or invariants, it giving us following error:

"The selected Primary Variable is not available in the current frame for any elements in the current display group. The selected Primary Variable is not available in the current frame for any elements in the current display group."

Is it not possible to view the contour results for Tensor quantities? If not possible then, this option (write Tensor data at nodes) doesn't make any sense in post-processing except that we can post-process using Abaqus Python APIs directly.
