**linear_rotation
#
Description#
This condition is a linearized version of the **rotation
boundary
condition (page ). For small deformation problems (not updated), this
condition should be used.
This version uses the approximation that angles will be small, so
Syntax#
The syntax is the same as for **rotation
. For 2D problems we have:
**linear_rotation [ node ]
For 3D problems, the syntax is slightly changed:
**linear_rotation [ node ]
See the discussion about rotation for more detail on the input structure.
