`**process antisymmetric_gradient`#

Description#

This post-processing step enables the computation of the antisymmetric part of the displacement gradient

**process antisymmetric_gradient $~\,~\,$ dimension (2 | 3)

dimension	input variable	output variable
2D	`U1`, `U2`	`gradU2_1`
3D	`U1`, `U2`, `U3`	`gradU2_1`, `gradU3_1`, `gradU3_2`

Note

This post-processing requires nodal values of displacement stored in .node or .ctnod files.

The following example can be found in $Z7PATH/TESTS/Post_test/INP/small_rotation.inp.
