WebThe Flexible Body Model Builder app generates the reduced-order model (ROM) data for flexible bodies by using the Craig-Bampton method [1]. WebThis model contains two element blocks, block 1 and block 2, which are the ‘nose’ and the ‘thrusters’ of the spaceship, respectively. The model also contains a single nodeset 1 which specifies the boundary nodes that will be retained in the Craig Bampton Substructuring. The attached Cubit input file will generate three exodus files.
