Controls how the software handles the torsion term in those codes that do not include it already by default.
If you select Default in this configuration setting, the software uses whatever the currently active piping code recommends. The power piping codes (such as B31.1) include torsion in the sustained and occasional stresses by explicitly including it in the stress equation (B31.1). The process piping codes (except for B31.3) do not include torsion in the sustained and occasional stresses by implicitly calling for longitudinal stresses only. To force CAESAR II to include the torsion term in those codes that do not include it already by default, select Yes.
In a sustained stress analysis of a very hot piping system subject to creep, it is
recommended that you include torsion in the sustained stress calculation using this
parameter in the setup file.
