OOF2: The Manual

The available output quantities now include the eigenvalues of symmetric tensors, such as stress and strain.

In the Analysis Page, Skeleton Edge and Point boundaries can be selected as the domain for an analysis operation. The output is computed on the Mesh Elements and Nodes corresponding to the Skeleton Elements and Nodes that make up the given boundary. Because Mesh Elements can have more Nodes than the corresponding Skeleton Elements, output from Point boundaries might not include all of the points that you think it might, and might not make sense unless the boundary consists of a single Node.
