# Orcaflex Modeling

## When to Use

- Setting up OrcaFlex analysis projects with standardized folder structure
- Running static or dynamic hydrodynamic simulations
- Batch processing multiple OrcaFlex models (.yml, .dat files)
- Configuring mooring analysis or iterative simulations
- Using the universal runner for pattern-based batch execution
- Preprocessing vessel data and checking model configurations
- Hydrodynamic analysis and mooring system design
- Riser analysis and installation sequence planning
- Fatigue assessment of offshore structures

## Prerequisites

- OrcaFlex license (checked via `OrcFxAPI`)
- Python environment with `digitalmodel` package installed
- YAML configuration files for analysis parameters
