Orcaflex Environment Config

When to Use

• Setting up wave conditions for simulations
• Configuring depth-varying current profiles
• Adding wind loads to vessel/structure analysis
• Defining seabed properties for touchdown regions
• Creating consistent environmental load cases
• Multi-directional wave/current combinations

Python API

Basic Environment Setup

from digitalmodel.solvers.fea_model.environment_components import Environment

def setup_environment(config: dict) -> dict:
    """
    Configure OrcaFlex environment from config.

    Args:
        config: Environment configuration dictionary


*See sub-skills for full details.*
### Direct OrcFxAPI Configuration

```python
import OrcFxAPI

def configure_orcaflex_environment(
    model: OrcFxAPI.Model,
    config: dict
) -> OrcFxAPI.OrcaFlexObject:
    """
    Configure environment directly in OrcFxAPI.


*See sub-skills for full details.*
### Current Profile Configuration

```python
import OrcFxAPI

def set_current_profile(
    model: OrcFxAPI.Model,
    surface_speed: float,
    direction: float,
    depth_factors: list
) -> None:
    """

*See sub-skills for full details.*
### Wind Configuration

```python
import OrcFxAPI

def configure_wind(
    model: OrcFxAPI.Model,
    speed: float,
    direction: float,
    reference_height: float = 10.0,
    apply_to_vessels: bool = True,
    apply_to_lines: bool = False,

*See sub-skills for full details.*
### JONSWAP Gamma Calculation

```python
import math

def calculate_jonswap_gamma(Hs: float, Tp: float) -> float:
    """
    Calculate JONSWAP gamma from Hs and Tp.

    Uses DNV-RP-C205 relationship.

    Args:

*See sub-skills for full details.*
### Multi-Directional Waves

```python
import OrcFxAPI
