User Manual

This section covers everything you need to set up, run, and analyse OASIS simulations.

Getting Started

  1. Running Simulations — command-line usage, folder conventions, input format auto-detection
  2. Input Format — overview of ASCII (.dat) and YAML input systems
  3. Input Reference — comprehensive field-by-field reference for all input files

Understanding Results

  1. Output Files — every output file produced by each module, with column descriptions

Learning from Examples

  1. Examples — 10 functional test groups with descriptions and setup instructions

Feature Guides

Detailed guides for each simulation subsystem:

  • Waves — regular, irregular (JONSWAP), time-series and frequency-domain wave input
  • Mooring Lines — dynamic FEM and quasi-static catenary solvers
  • Springs & Connectors — linear/nonlinear connectors with friction
  • Winches — winch-controlled mooring with tension and position controllers
  • Oscillating Water Columns — OWC chamber dynamics and turbine coupling
  • Wind Turbines — OpenFAST aero-servo-elastic coupling
  • ODE Solvers — BDF and ESDIRK time integration methods
