# Orcaflex Batch Manager

## Wiki Context (query before execution)

Before starting a batch simulation campaign, query the wiki for relevant domain knowledge:

```bash
bash scripts/knowledge/wiki-query-context.sh "OrcaFlex batch simulation" --domains engineering,marine-engineering
```

Check results for: solver settings, convergence guidance, known pitfalls, and related standards.
Log consulted wiki pages in your output per the retrieval contract (#2208).

## When to Use

- Running large simulation campaigns (100+ cases)
- Parallel processing of multiple OrcaFlex models
- Sensitivity studies with many parameter combinations
- Operability matrices covering many sea states
- Multi-seed Monte Carlo simulations
- Overnight batch processing with monitoring

## Python API

### Basic Batch Processing

```python
from digitalmodel.orcaflex.universal.batch_processor import BatchProcessor
from pathlib import Path

def run_batch(input_dir: str, output_dir: str, max_workers: int = 20):
    """
    Run batch processing on OrcaFlex models.

    Args:
        input_dir: Directory containing model files

*See sub-skills for full details.*
### Adaptive Parallel Processing

```python
from digitalmodel.orcaflex.universal.batch_processor import BatchProcessor
from pathlib import Path
import psutil

class AdaptiveBatchProcessor(BatchProcessor):
    """Batch processor with adaptive resource management."""

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

*See sub-skills for full details.*
### Chunk-Based Processing

```python
from digitalmodel.orcaflex.universal.batch_processor import BatchProcessor
from pathlib import Path
import time

def process_in_chunks(
    input_dir: str,
    output_dir: str,
    chunk_size: int = 50,
    pause_seconds: int = 5

*See sub-skills for full details.*
### Progress Tracking and Checkpoints

```python
from digitalmodel.orcaflex.universal.batch_processor import BatchProcessor
from pathlib import Path
import json
import time

class CheckpointBatchProcessor(BatchProcessor):
    """Batch processor with checkpoint save/restore."""

    def __init__(self, checkpoint_file: str = "batch_checkpoint.json", **kwargs):

*See sub-skills for full details.*
### File Size Optimization

```python
from pathlib import Path
import os

def sort_by_file_size(files: list, reverse: bool = True) -> list:
    """
    Sort files by size for optimal processing order.

    Processing large files first with fewer workers,
    then small files with more workers.

*See sub-skills for full details.*
### Performance Metrics

```python
from dataclasses import dataclass, field
from typing import Dict, List
import time
import json

@dataclass
class BatchMetrics:
    """Track batch processing performance metrics."""


*See sub-skills for full details.*
