Common modal decomposition techniques for flowfield analysis, data-driven modeling and flow control, such as proper orthogonal (POD) dynamic mode (DMD) are usually performed in an Eulerian (fixed) frame of reference with snapshots from measurements or evolution equations. The description poses some difficulties, however, when the domain mesh deforms time as, example, fluid-structure interaction...
