The FE Part is a wholly Adams-native modeling object with inertia properties and is accurate for very large deformation cases (that is, geometric nonlinearity) of beam-like structures. The FE Part differs from the linear flexible body option within Adams Flex in two significant ways: 1) it has the ability to accurately represent large deformations which the linear modes approach cannot and 2) its modeling does not require an FEA-produced file like the modal neutral file (MNF). The FE Part also differs from the beam force element in that it possesses inertia properties. The inertia properties are specified using symmetric, consistent mass matrix which remains constant.
