### Function Variable

![](https://img.shields.io/badge/-public-brightgreen "public")

```cpp
sysc::Variable::Variable(const VariableName &name, enum QuantityType quantityType, enum Location location=Node, const DisplayName &displayName=DisplayName())

```

Provide a constructor for the [Variable](classsysc_1_1Variable.md#classsysc_1_1Variable) class.

**Parameters**:

- **name**: - Unique name for this variable.
- **quantityType**: - Quantity type of this variable. Supported quantity types are defined above in this header file.
- **location**: - variable location (e.g element or node). This parameter is optional - the default value is node.
- **displayName**: - variable display name. This parameter is optional - it will default to the same value as the variable's name.

Note that provided quantity type will determine the value of the tensor type and is extensive parameters. The values will be inferred according to the following rules:

```cpp
Quantity Type                     Tensor Type      Is Extensive
----------------------------------------------------------------
Force                             Vector           True
Incremental Displacement          Vector           False
Temperature                       Scalar           False
Heat Rate                         Scalar           True
Heat Transfer Coefficient         Scalar           False
Convection Reference Temperature  Scalar           False

```

For a more explicit control of tensor type and is extensive values, consider using another constructor.

DataType will default to real.
