Abaqus delivers all data to represent flexible bodies. Mass and stiffness matrix, nodal coordinates, element connectivity and Ritz vectors. The latter ones are used to assign the columns of a transformation matrix in a combined Guyan/modal reduction scheme which is used to reduce the number of dofs adequate for dynamic simulations in the time domain.
Thus our customers can use reduced flexible bodies based on Abaqus, when using one of our dynamic simulation tools FIRST, PIMO3D, TOWER.
