Thanks for your respond. I knew this option but it is not what I meant. in workbench we can see also the Nodal Solution and Element Solution as well as APDL. For example the von Mises Stress Element Solution in APDL is similar to von Mises Stress (unaveraged) in WB. For Nodal Solution we need to averaged result.
The difference between APDL and WB is, in Nodal Solution in APDL when the PowerGraph is On or Off. Then you will have different value in result and this is due to singularity in model. if you have fine mesh all this values must be roughly same.
To understand the result we need to first understand the difference between Nodal and Element Solution.
