Predefined Physics Variables
Physics variables are predefined variables that the physics interfaces introduce. They are typically functions of the dependent variables and their derivatives. Many of these variables are available in the Predefined quantities lists in the settings for plots and other results nodes.
To access physics variables, use a variable scoping syntax that uses the Name to indicate the physics that they belong to.
The Equation View subnode is available for all physics nodes and contains a table with the names, expressions, units, and descriptions for the physics variables that the node defines. To display the Equation View subnodes, click the Show More Options button () and select Equation View in the Show More Options dialog.
