Services > Multibody Dynamics
METECS personnel are among the pioneers of flexible multibody dynamics and the current developers and maintainers of MBDyn, the dynamics engine NASA employs to simulate and analyze space robotics, orbital mechanics, constrained motion, and more.
METECS is the developer and maintainer of NASA's MBDyn dynamics engine. MBDyn is an open source, highly optimized, configurable dynamics engine that NASA uses to simulate and analyze rigid and flexible multibody systems. The simulated systems may consist of multiple groups of articulated chain, tree, or closed-loop topologies. Transient topologies are handled with conservation of energy and momentum. The solution for rigid-body systems is exact and several configurable levels of non-linear term fidelity are available for flexible multibody systems. The algorithms have been optimized for efficiency and can be used for both nonreal-time and real-time simulations. Contact METECS to find out how we can leverage MBDyn's years of development and testing to solve your dynamics simulation needs.
