About Modelica Components

Modelica Text

In Modelica, a replaceable component is declared in the following way:

class C1

replaceable MyClass M1;

end C1;

The component can be replaced either in another class that extends C1:

class C2

extends C1(redeclareMyOtherClass M1);

end C2;

or by creating a component from C1:

class C2

C1 c1comp(redeclare MyOtherClass M1);

end C2;

When replaced, M1 attributes are modified in both C1 and C2. Note that you can edit only components that have a graphical representation.

It is also possible to set constraints on which the class of the replaceable component can be replaced with:

class C3

replaceable MyClass M1 constrainedby MySpecialClass;
 

end C3;

For more information about the capabilities and attributes of replaceable and replaced components, refer to the Modelica specification.
