二維轉子動力學模型不僅可以用于系統的簡化分析，也可以對其進行超單元生成，然后作為次級部件導入其他系統模型中。需要指出的是，超單元生成的計算，沒有任何可以顯示的三維結果。

通過對本案例的介紹，可以了解到samcef在超單元生成方面的功能，主要包括：

· Howto define 2D rotor geometry in Field (vertex, lines, face)

· Howto define an elastic material

· Howto create a superelement from this 2D geometry

· Howto create a model, and import the superelement in it

· Howdo define a Lumped mass attached to the superelement

· Howdo define a Ground bearing linked to retainednodes of the superelement

· Howdo define locking on translational degrees of freedom of the superelement

· Howto perform a “critical speed” analysis (ROTOR) of the model containing thesuperelement

· Howto examine the results and report them.
