Description: The extrapolation and interpolation schemes were changed in Abaqus/Standard for three commonly used output variables—stress, Mises equivalent stress, and equivalent pressure stress—to reduce the size of the output database. In the old scheme extrapolation or interpolation was performed after the analysis finished and required storage of stresses at integration points. In the new scheme the extrapolation or interpolation is performed as soon as the results are available during the analysis, and only the results at the requested locations are written to the output database. The new scheme is invoked automatically when output is requested for any of the supported variables. In the case of Mises equivalent stress and equivalent pressure stress the new output variables, MISESONLY and PRESSONLY, must be used. If output variables MISES and PRESS are used instead, the old scheme is invoked.

In addition, an enhancement was implemented in both Abaqus/Standard and Abaqus/Explicit that allows you to easily request output on the exterior node and element sets. This option is available only for three-dimensional models and is particularly useful for visualization of the overall deformation of the model.
