•Navier Stokes solver based on FFT and assumes periodic boundary conditions.
•N-S solver used 256 x 512 Eulerian mesh
•Used 5332 particles to model the 2D vocal folds with distance between particles = h/4
•IB method computes velocity field, pressure field, and the motion of the model folds as one coupled system
•Here as an illustration we render velocity field and vorticity and marker motion as (animated gif) movies
