**process symmetric_gradient

Description

This post-processing step enables the computation of the symmetric part of the gradient of the displacement ( or any vector-valued variable)

Syntax

**process symmetric_gradient \(~\,~\,\) *var var_prefix

*var var_prefix

is the name of the variable for which the symmetric gradient is computed.

Note

The output variables are eto11, eto22, eto33, eto12 for 2D (eto23, eto31 in addition for 3D case). The eto prefix is used consistently, even for variables not related to displacement.

Example

****post_processing
 ***global_post_processing
  **file node
  **nset ALL_NODE
  **process symmetric_gradient
   *var U
****return
