nRead my January 3 reply in this discussion: for an example of Averaged, Unaveraged and Nodal Difference.nIf you used shared topology to break a single part of the same material up into many bodies to help make a good mesh, you should choose YES for Average Across Bodies.nIf adjacent bodies have different materials, then choose NO for Average Across Bodies. For example, if you used shared topology to separate a thick surface coating modeled as a thin solid from the underlying solid of a different material, you want to see the stress computed in each material separately and there is a real physical discontinuity of stress at the interface that you don't want to average away.n
