Flexible Bodies in EasyDyn from Abaqus

Successful import of a flexible part from Abaqus to EasyDyn implementing the corotational formulation in minimal coordinates. Mass and stiffness matrices are generated from Abaqus and read by EasyDyn. The latter eventually builds the superelement.

Application: integration of flexible bodies in multibody simulations with less degrees of freedom if the flexible part is reduced in the first place (in the finite element model). Hence, less equations need to be solved yielding fast and still accurate simulations.
