#### *class* Ansys.ACT.Mechanical.Fields.Variable

Bases: [`object`](https://docs.python.org/3/library/functions.html#object)

Represents an object that is either an input or an output for a P:Ansys.ACT.Mechanical.Fields.Variable.Field. Depending on whether it is an input or output and on the way it is defined, this object holds a series of discrete values or an expression that may involve other variables.
