## About this Block

The **Implicit Body from Field Optimization** block is used in field optimization to extract the Implicit Body from Field Optimization Result.

***

Extract an Implicit Body from a Field Optimization result.

### Inputs

| Name         | Type                                                                                         | Description                                                                                                        |

| Result       | [Field Optimization Result](../../../../block-documentation/types/field-optimization-result) | Result to extract surface from.                                                                                    |
| Iteration    | [Integer](../../../../block-documentation/types/integer)                                     | Iteration number which the Implicit Body will be extracted from. If not provided, the last iteration will be used. |
| Domain index | [Integer](../../../../block-documentation/types/integer)                                     | Domain index which the Implicit Body will be extracted from. If not provided, the first Domain will be used.       |
