Specifies the hanger stiffness for the load case. The three options are: As Designed, Rigid, and Ignore.

As Designed

Causes the software to consider the actual spring hanger stiffnesses. Use this option for most real (non-hanger design) load cases.

Rigid

Causes the software to model the spring hangers as rigid restraints. Use this option for restrained weight cases and hydrotest cases if the spring hangers are pinned.

Ignore

Causes the software to remove the spring hanger stiffnesses from the model. Use this option for hanger travel cases, unless you want to include the stiffness of the selected spring in the operating for hanger travel case and iterate to a solution. In that case, select As Designed. You must also adjust the hanger load in the cold case (in the physical system) to match the reported hanger cold load.

User-defined hangers are not made rigid during restrained weight cases.
