Getting Started

This page describes the main steps needed in order to run your first set of aeroelastic simulations using Spawn Wind

1. Edit the spawn.ini file to refer to the desired FAST base input files and working directory. A description of configuration options is here. They are currently set up to use the NREL 5MW input files located in the example_data/fast_input_files directory.

2. Write a Spawn input specification in JSON (file format definition here). The parameters should correspond to properties of the spawner (documented here), e.g. wind_speed, simulation_time.

   • There is an example IEC spec in the repository which produces an example set of IEC load calculations. This is an example only and not Simmovation’s official interpretation of the IEC standard so users should write their own IEC spec according to their needs and turbine.

   • Note in particular the path policy in the input file definition. This is used to specify the output directory of simulations.

   • Users can inspect their parameter specification and associated paths of simulations using the inspect command - spawnwind inspect [specfile].

3. Execute simulations using the run command - spawnwind run [specfile] [outdir]
