intermediates
Define intermediate terms for use in equations
Parent Section: component | domain
Syntax
intermediates int_term1 = expr1; end
Description
intermediates
begins an intermediates declaration
block, which is terminated by an end
keyword. In a component file,
this block contains declarations of named intermediate terms for use in equations. You
can reuse these intermediate terms in any equations
section of the same component or an enclosing composite component.
You can also include an intermediates
section in
a domain file and reuse these intermediate terms in any component that has nodes of that
domain type.
When you use an intermediate term in an equation, the equation substitutes the intermediate term with the expression that it refers to. Think of an intermediate term as of defining an alias for an expression.
intermediates
int_term1 = expr1;
end
Declaring intermediate terms helps with code reuse and readability. For example, if you declare hydraulic diameter and critical Reynolds number as intermediate terms in an isothermal liquid component, you can then use these terms throughout the component equations.
You can specify a descriptive name for an intermediate term, by using a comment, similar to the way you do it for parameters and variables:
intermediates
int_term1 = expr1; % Descriptive name
end
If you include the intermediate term in logged simulation data, this descriptive name
appears in the Simscape™ Results Explorer. You can also specify a preferred data logging unit for
intermediate terms by using the LoggingUnit
annotation. For more information, see Specify Preferred Logging Unit for an Intermediate.
