Basic Model Concept:Bend

Bend applied at TO nodeBasic Model Concept:Rigid Element with Weight

Rigid Element w/ WeightNormally for Valves and FlangesCAESAR II automatically includes 1.0 times the fluid weight of equivalent straight pipe and 1.75 times the insulation weight of equivalent straight pipe.Basic Model Concept:Rigid Element without Weight

Rigid elements with zero weight are considered to be modeling constructs and do not have fluid or insulation weight added.

Rigid Element w/o WeightNormally for Representing Equipment Thermal ExpansionBasic Model Concept:Flexible Element

If the torsional stiffness value is not specified, CAESAR II uses a default value of 0.11298E+05Use 1.0 for bellows stiffnesses that are completely flexible.Use 1.0E12 for rigid bellows stiffnesses.Flexible Element Normally for Expansion JointBasic Model Concept:Reducer
