EAS102, December 2005 Copyright© 2005 MSC.Software Corporation Chart 21 • Connections between the GP components are usually the connection of a single output of the “from” component to a single input of the “to” component. •A strength of MSC.EASY5 ported connections is the ability to use a single graphical connection line to represent a physical association between two components of a physical system. Examples: Hydraulic fluid flowing from a valve into a heat exchanger Electric power flowing from a transmission line to a transformer Mechanical power flowing from a drive shaft to a differential • Modeling these associations requires multi-variable, bi-directional information passing between the component models. Example (Hydraulic connection - simplified): Model Building Complex Connections
Building Models Port connections A component port is a collection of variables(both inputs and outputs) grouped to represent a physical connection a port connection between a port on one component to a port on a second component consists of: A connection of each output variable of either port to the input of the other port with the same variable identifier(ignoring the port name) Each port has a unique alpha-numeric name Port name is the portion of variable name between the two underscores Example:sIn iN is the inlet signal for the GP/N integrator component Component name put nar Each port also has a number that is used internally by MSC.EASY5 Connection scheme Conventional names Wfor flow rate, etc )and ports make automatic connection possible Also can check for complete connection -ie. won't misconnect W= flow rate to W=shaft speed because rest of port names dont match EAS102.
