Introduction – Physical modeling
Behind the icons
• System simulation is linked to the power flow and power conservation
within a system
• Each power network can be modeled using different physics with gates for
sub-system connections
You are manipulating equations not drawing a circuit !

Hydraulics Solution
LMS Amesim libraries
The components are defined by their hydraulic characteristics
usually provided by the component supplier
"basic element library" made of "physical functions" to build
detailed models of. The models are based on their geometry and
physical properties (mass, spring stiffness, …)
Libraries designed especially for the evaluation of pressure
losses and flow rate distribution in hydraulic networks.
