Orcaflex Vessel Setup

When to Use

• Creating new vessels in OrcaFlex models
• Configuring 6-DOF motion properties
• Importing vessel hydrodynamics from AQWA
• Setting up vessel calculation options
• Defining vessel types with RAO data
• Configuring drift, damping, and wave loads

Python API

Basic Vessel Creation

from digitalmodel.solvers.fea_model.Vessel_components import Vessel
from digitalmodel.solvers.fea_model.VesselType_components import VesselType

def create_vessel(config: dict) -> dict:
    """
    Create OrcaFlex vessel configuration.

    Args:
        config: Vessel configuration dictionary

*See sub-skills for full details.*
### AQWA Vessel Import

```python
from digitalmodel.solvers.fea_model.preprocess.load_vessel import LoadVessel
import OrcFxAPI

def import_vessel_from_aqwa(
    model: OrcFxAPI.Model,
    aqwa_file: str,
    vessel_name: str,
    import_config: dict = None
) -> OrcFxAPI.OrcaFlexObject:

*See sub-skills for full details.*
### Vessel Calculation Settings

```python
import OrcFxAPI

def configure_vessel_calculations(
    vessel: OrcFxAPI.OrcaFlexObject,
    settings: dict
) -> None:
    """
    Configure vessel calculation options.


*See sub-skills for full details.*
### Multi-Body Import

```python
import OrcFxAPI

def import_multi_body_system(
    model: OrcFxAPI.Model,
    aqwa_file: str,
    body_mapping: list
) -> dict:
    """
    Import multi-body system from AQWA.

*See sub-skills for full details.*
