Fuel acquisition is one of many challenges FLOW-3D can solve. Due to the complexity of the maneuvers and the interaction of fuel dynamics with the spacecraft dynamics FLOW-3D is well suited to model operations such as fuel acquisition shown here. Any maneuver can be simulated using its non-inertial reference frames and coupled rigid-body dynamics. The motion and position of fuel in a microgravity environment is accurately simulated with powerful surface tension and wall adhesion model.
