Simulations demonstrate that fast magnetoacoustic waves incident on a localized coronal null undergo mode conversion to produce incompressible energetic Alfvén wave packets along separatrices.
Fast magnetoacoustic waves steepen and dissipate nonlinearly before reaching coronal magnetic null points due to decreasing fast speed in the non-uniform magnetic field.
