Abstract
The goal of the project is to develop geometric numerical integrators on manifolds for the
purpose of stable and numerically efficient dynamic simulation of the constrained multibody
systems, with a special focus on flight vehicle dynamics and related multibody systems (elastic
wind-turbines, mechatronical and biomechanical systems, terrestrial vehicles, space satellites
etc.). The project will allow for continuation of the successful scientific collaboration with the
international partners and will enable Laboratory of Flight Vehicle Dynamics and Structural
Systems (Faculty Mech. Eng. & Naval Arch., Univ. Zagreb) to maintain and improve scientific
excellence in the targeted field through the scientific collaboration with the distinguished EU
scientists and research institutions. Also, the project will improve strategical bonds between
Faculty Mech. Eng. & Naval Arch and industrial subjects that are active in domain of industrial
simulations. After evaluation of the chosen ODE integrators on Lie groups in the context of their
application within the framework of integration of dynamics of rigid and elastic bodies, the
geometric numerical integration algorithms on manifolds will be designed and applied on
dynamics simulation of the chosen engineering systems (dynamic simulator of the flight vehicle,
elastic wind-turbine). Numerical characteristics of the developed geometric algorithms will be
evaluated and compared with the characteristics of the 'classical' DAE (differential-algebraic
equations) solvers that operate in the vectorial spaces. It is expected that the geometric
algorithms will perform better in terms of numerical accuracy, stability and efficiency within the
context of the targeted tasks. The chosen numerical simulation procedures will be implemented
in the OpenFoam simulation package, what will give an opportunity for a wide dissemination and
a usage of the project results within a scientific and industrial community.
