The equation defining the physics node can be edited with the method featureInfo('info') applied to a feature of the physics node
physics(<phystag>
).feature(<ftag>), where
<phystag> and
<ftag> identify the physics interface and the feature, respectively:
Use the method getInfoTable(type) to return the tables available in the Equation View node:
where type defines the type of table to return. It can have the value
'Weak' to return the weak form equations,
'Constraint' to return the constraint types table, or
'Expression' to return the variable expressions table.
From the info object access the weak form equation by entering:
To access the equation in the node root.comp1.ht.solid1.weak$2; for example, to modify the equation and lock the expression, run the commands:
