Modified version OpenFAST v3.0.0 (Implementation of multi-support seismic input motion and soil-structure interaction)

This repository contains a modified version of OpenFAST 3.0.0 in which the Subdyn module has been modified to include the two following features:

  • Multi-support Seismic foundation input motions at the base of the support structure.
  • A dynamic soil-structure interaction model that employs a Simplified Lumped Parameter Model to represent the lateral, vertical, rocking and torsional impedances of the foundation.
