not drawing a circuit !

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



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.
