Top: Grid independence study results for model with 99% stenosis, comparing glottal width for three grid densities during the first 0.04 sec of the simulations: ––––– Model grid density, - - - - - - - Grid-halved density, – – – – - Grid-doubled density. Bottom: Glottal width waveforms plotted over a steady state cycle, comparing two grid densities for the model with 99% stenosis: ––––– Model grid density, – – – – - Grid-doubled density.
