Orcawave To Orcaflex

When to Use

• Converting OrcaWave results (.owr) to OrcaFlex vessel type
• Creating hydrodynamic database for time-domain analysis
• Importing RAO data from diffraction analysis
• Adding viscous damping to radiation damping
• Transforming coordinate systems between tools
• Setting up vessel types with full hydrodynamic properties
• Batch conversion of multiple loading conditions

Python API

Basic Conversion

from digitalmodel.diffraction.orcawave_converter import OrcaWaveConverter
from digitalmodel.diffraction.orcaflex_exporter import OrcaFlexExporter

# Load OrcaWave results
import OrcFxAPI

# Option 1: From OrcaWave model directly
orcawave_model = OrcFxAPI.DiffractionModel("models/fpso.owr")
vessel = orcawave_model.Vessel

*See sub-skills for full details.*
### With Viscous Damping

```python
from digitalmodel.orcawave.orcaflex_export import OrcaWaveToOrcaFlex

# Initialize converter with damping options
converter = OrcaWaveToOrcaFlex()

# Load OrcaWave results
converter.load_orcawave("models/fpso.owr")

# Add viscous damping (percentage of critical)

*See sub-skills for full details.*
### Full Hydrodynamic Database

```python
from digitalmodel.orcawave.orcaflex_export import HydrodynamicDatabaseCreator

# Create complete hydrodynamic database
db_creator = HydrodynamicDatabaseCreator()

# Load all loading conditions
db_creator.add_condition(
    name="full_load",
    orcawave_file="models/fpso_full.owr",

*See sub-skills for full details.*
### RAO Import with Validation

```python
from digitalmodel.orcawave.rao_import import RAOImporter
 digitalmodel.diffraction.output_validator  OutputValidator


importer = RAOImporter()


raos = importer.load_from_orcawave()


*See sub-skills  full details.*


```python
 digitalmodel.orcawave.coordinate_transform  CoordinateTransformer


transformer = CoordinateTransformer()



transformer.set_orcawave_origin(
    x=,
