Specifies the circumferential stiffness at the nozzle and across the pipe cross-section, as calculated using another method.

Mo - Out-of-Plane Bending (circumferential stiffness)

Fax - Axial (Nozzle) (radial stiffness)

Mi - In-plane Bending (longitudinal stiffness)

Mt - Torsional (Nozzle) (torsional stiffness)

D - Direction cosine of shell

Represents a nozzle on any type of head.

Mo - Out-of-Plane Bending (circumferential stiffness)

Fax - Axial (Nozzle) (radial stiffness)

Mi - In-plane Bending (longitudinal stiffness)

Mt - Torsional (Nozzle) (torsional stiffness)

D - Direction cosine of head

For a nozzle in the center of the head, in-plane and out-of-plane stiffness are the same due to symmetry.
For a hillside (off-center) nozzle, you should apply stiffness in the proper direction.

If you do not define a stiffness value, the software uses the default rigid stiffness.
