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
digitalmodelpackage 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.*
