The Simcenter Amesim™ software interface allows the user to connect a 3d mechanism model built in Simcenter 3D Motion with a Simcenter Amesim model. This interface (called Mechatronics) is useful when studying the interaction between complex mechanism models and sophisticated pneumatic and hydraulic systems.

The power of this interface allows the user to take advantage of the strengths of both Simcenter Amesim and Simcenter 3D Motion. The interface has been designed to not diminish the strengths of either package, but instead to enhance them. The interface will allow the user to plot each system's results in its own package and to take full advantage of the animation capabilities of Simcenter 3D Motion.

The Simcenter 3D Motion to Simcenter Amesim interface supports the following types of analysis.

Analysis Type	Master solver	Where solution is started	Sub-Analysis Types
Coupled dynamic solution	Simcenter 3D Motion	Simcenter 3D Motion	Dynamics Static/Dynamic
Co-Simulation	Simcenter Amesim	Simcenter Amesim	Dynamics
Co-Simulation	Simcenter 3D Motion	Simcenter 3D Motion	Dynamics

Table 1

As shown in Table 1 a number of different analysis types are supported. The Simcenter 3D Motion/Simcenter Amesim solution process is a master/slave relationship. In the coupled solution all of the Simcenter 3D Motion equations and Simcenter Amesim state equations are combined and solved simultaneously. This also allows the Simcenter 3D Motion static solver and linearization to be used. In co-simulation mode the Simcenter 3D Motion model is exported from Simcenter 3D Motion and added as a submodel into Simcenter Amesim. This is strictly a co-simulation. The coupled simulation environment will allow some other Simcenter 3D Motion-type analysis to be used: statics, dynamics, static/Dynamics and linearization.

Dynamic Solution - In a dynamic solution the underlying differential-algebraic equations of motion are solved by a numerical integration process.

Static/Dynamic Solution - In this analysis solution, first a static solution is done to bring the equations of motion to equilibrium then a dynamic solution is launched starting from the equilibrium position.
