什么是 superelement ??

5.2. Flexible Body Types

A multibody simulation supports two types of flexible bodies:

Bodies that are excited by the motion of other bodies (rigid or flexible) but do not themselves undergo large motions

An engine block is an example of this type, where the block is excited dynamically from the crankshaft, pistons, and other moving parts attached or linked to the block. This case is a straightforward application of traditional superelements.

Bodies that are undergoing large motions

A piston rod is an example of a body undergoing large motions; this type also uses superelements but with the additional capability that the superelement can undergo large motions, and large rotations in particular. A large-rotation superelement involves additional considerations.

就象分块矩阵一样。把一个矩阵分成几个小矩阵。小矩阵里面又包含更小的矩阵或元素。超元就是把几个单元类型（或超元）组成一个单元
