Controls the use of in-plane and out-of-plane SIFs. The EN-13480 piping code (and other European piping codes) defaults to the use of a single SIF, applied to the SRSS of all three bending moments. Optionally, you can utilize distinct in-plane and out-of-plane SIF values for in-plane and out-of-plane moments.
To use distinct in-plane and out-of-plane SIFs, select True.
