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
from digitalmodel.diffraction.output_validator import OutputValidator
# Import RAOs with validation
importer = RAOImporter()
# Load OrcaWave RAOs
raos = importer.load_from_orcawave("models/fpso.owr")
*See sub-skills for full details.*
### Coordinate Transformation
```python
from digitalmodel.orcawave.coordinate_transform import CoordinateTransformer
# Handle coordinate system differences
transformer = CoordinateTransformer()
# OrcaWave uses different conventions than OrcaFlex
# Transform origin location
transformer.set_orcawave_origin(
x=150.0, # Midship
*See sub-skills for full details.*
