Evaluate an expression with local variables.

### Inputs

| Name           | Type                                                           | Description                                                                                          |
| -------------- | -------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- |
| Expression     | [Text](../../../../block-documentation/types/text)             | Expression to evaluate.                                                                              |
| Dimensionality | [Scalar](../../../../block-documentation/types/scalar)         | A scalar variable representing the expected dimensionality to which the expression should evaluate.  |
| Variables      | [Dictionary](../../../../block-documentation/types/dictionary) | Dictionary defining the name and corresponding scalar field value of each variabe in the Expression. |

### Outputs

| Type                                                               |

| Dimensionality | [Scalar](../../../../block-documentation/types/scalar)             | A scalar variable representing the expected dimensionality to which the expression should evaluate. |
