The mechanics solution in GT-SUITE is based on a formal 3-D multi-body dynamics formulation, capable of modeling any mechanical system.
Among the technical features and advantages are:
Physics features:
- 3-D/2-D rigid and flexible-body MBD, 1-D translational and rotational element libraries
- Specialized libraries for cranktrain, valvetrain, timing drives, transmission
- Library for planar mechanism kinematics
- Linear frequency-domain solution
- 3-D and 2-D contacts and constraints, contact tribology
- Flexible bodies : large-deformation non-linear FE, connectivity to rigid bodies
- Flexible bodies : automatic (built-in) static and modal harmonic reduction
- Tightly integrated with GT-SUITE 1-D flow and other physical domain solutions
- Film hydrodynamics solution and elements (journal, slider, piston, thrust bearings, etc.)
Solution numerics and user productivity features:
- Fast execution speed, superior stability
- Dynamic memory, model size limited only by hardware
- Sparse matrix (profile) optimization technology
- Many speed-up features (circuit technology, fast 1-D solutions, 1D/2D, 2D-3D transition)
- Choice of 7 ODE integrators (2 explicit, 5 implicit)
- MBD models from 3-D CAD and auto-meshing for flexible bodies
- 3-D animations, including 3-D CAD/FE representations
Broadly applicable to any mechanical system, and a wide variety of applications. Easy integration into high-level system models, as well as into very detailed models suited for root cause investigations.
