Fast, scalable and accurate
AgX Dynamics is a professional multi-purpose physics engine for simulators, engineering, large scale granular simulators and more. It consists of hundreds of C++ classes of highly optimized and portable code and is the obvious choice when you need to simulate mechanical constrained systems with frictional contacts. It is truly scalable in all senses of the word. Built upon a solid foundation of original scientific research, including discrete variational and physics based time integration methods for constrained systems, parallel high performance hybrid equation solvers and novel multi-physics models. Therefore AgX Dynamics combines accuracy with speed in a way that cannot be found in any other competing physics engine or product.

Lumped elements modelling
This video demonstrates the power of the constraint modelling paradigm together the the fast direct solver. A lumped element model with relaxed LockJoints give you an elastic model of a cable including bending, drag and torsion.
Wires and cables
This video shows our wire simulation technologies in action. The wire simulations in AgX Dynamics are fast enough for demanding real time simulators and yet the models have high physical accuracy and are stable under extreme loads and mass ratios. Dynamic resolution which depends on load and curvature ensures stable simulations. Wires can be tuned to represent ropes, wires and chains with realistic material parameters including bend and stretch Young’s modulus.
The wire contains functionality such as:
- Wires with detailed material specifications.
- Winches with speed and tension control.
- Wires can be cut into separate wires or merged into one.
- Wires realistically interact with other objects.
- Dynamic and user controlled resolution allow for large scalable scenarios with kilometers of wire.

CAD to simulator
AgX Dynamics is very strong in delivering dynamics simulations to simulators. By being part of the process from CAD to training simulator, models can be reused through out the process. Through the serialization mechanism in AgX Dynamics a CAD model in Dynamics for SpaceClaim with dynamic properties such as joints, motors, physical materials, mass, inertia tensor etc. can be instantly exported into a run-time environment.
Simulation in product development
Simulation is an important part of the whole product development process. By allowing more people to do early prototype simulations, early design errors are reduced. With AgX Dynamics integrated into your CAD environment, you can run mechanical simulations on your design, all the way from prototype stage through system engineering to marketing and training simulators.
