Orcaflex Post Processing

When to Use

• Extracting summary statistics from simulation results
• Creating range graphs for motion/load envelopes
• Generating time series plots for specific variables
• Computing linked statistics (correlations between variables)
• Creating histogram distributions of results
• Building interactive HTML dashboards from simulation data
• Batch processing multiple .sim files in parallel

Prerequisites

• OrcaFlex license (for reading .sim files)
• Completed simulations in .sim/ directory
• Python environment with digitalmodel package installed

Python API

Basic Post-Processing

from digitalmodel.orcaflex.opp import OrcaFlexPostProcess

# Initialize post-processor
opp = OrcaFlexPostProcess()

# Load configuration
cfg = {
    "orcaflex": {
        "postprocess": {

*See sub-skills for full details.*
### Batch Processing with Parallel Execution

```python
from digitalmodel.orcaflex.opp import OrcaFlexPostProcess
from concurrent.futures import ProcessPoolExecutor
from pathlib import Path

opp = OrcaFlexPostProcess()

# Get all .sim files
sim_files = list(Path("results/.sim/").glob("*.sim"))


*See sub-skills for full details.*
### Extract Specific Results

```python
from digitalmodel.orcaflex.orcaflex_utilities import OrcaflexUtilities

utils = OrcaflexUtilities()

# Load simulation
model, metadata = utils.get_model_and_metadata("simulation.sim")

# Get time history
line = model["Line1"]

*See sub-skills for full details.*
