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.*
