SOLID72和SOLID73擁有轉動自由度，便于和梁、殼單元結合，在Ansys單元手冊中，沒有這兩種單元的詳細描述，下面為SOLID72和shell63結合計算的簡單算例。

The test problem below illustrates this. A one inch wide model with a
modulus similar to aluminium starts with a 1 inch cube of SOLID72
elements. From the centre of this projects a 29-inch long SHELL63
beam. The shells and SOLID72 elements are connected simply by their common
rotational DOF. A 10-psi pressure is applied to the shell elements, which
produces a moment of about 4500 in-lb at the connection to the SOLID72
elements. This results in approximately a 12.5-degree rotation between
the SOLID72 portion of the model and the shells. This actually appears to
be a local rotational deformation in the immediately adjacent SOLID72
elements. The SOLID72 elements do not provide full moment
continuity. They will prevent a complete hinge, however, and this
modelling technique may be adequate in some cases.

solid73單元在GUI里面沒有，要用命令流來操作。
