4. Partition To simulate a component the user first has to define its associated mathematical model this is called a partition A component may have more than one partition For example if a component has several different boundary conditions depending on the set of variables selected each set of variables produces a different mathematical model or partition The next step is to generate experiments for each partition The partition defines the causality of the final model External connections Overview of the program Page 21 Experiment The experiments performed for each partition of the component are the different simulation cases They may be trivial for calculating a steady state or very complex with many steady and transient states changing multiple variables in the model Library of components All the components are classified by disciplines into libraries 7 4 Working in EcosimPro A EcosimPro component can be built either from scratch or formed from basic predefined components The components are taken either from a system library or are defined by the user Each component contains a mathematical description of the real world component it represents Components have interfaces with each other by means of connection ports Components can be joined together by their ports to form a new component EcosimPro is hierarchical in the sense that models may also have ports and so can be joined to other components to create more com
