System Coupling provides an easy and systematic workflow to transfer mode shapes from a Mechanical modal analysis to a CFD analysis for Aerodynamic Damping analysis (also known as "Aerodamping" or "Blade Flutter" analysis).

System Coupling maps the mode shapes from the Mechanical modal analysis surface mesh to a CFD surface mesh. It provides geometry alignment, interface instancing, unmapped value handling, as well as other functionality. The mapped mode shapes are written to .csv file(s) that can be used to provide displacements for a CFD analysis.
