Nodal Solution (von Mises Stress)- Workbench

      I have done calculation in Ansys APDL. In order to use FKM tool, I imported the model in Wrokbench as *.cbd external model. In Workbench I read the results as .rst file . After evaluting the results in both platforms (APDL, Workbench), I coulde see that, the von Mises stress (Unavraged)in Workbench is identical to Element solution in APDL.

      due to my Project I need to validate the Nodal stress in both Platform (APDL, Workbench). Does anybody know that, how can I read Nodal Solution in Workbench?

      Select the nodes and then evaluate the stress result for the nodes.

      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.

      Greetings,

       

      Our engineering specifically covered this topic in a support article titled, Ansys Workbench Mechanical: Averaged vs. Unaveraged Contour Results.
