      The command MP,VISC can be used to include bulk viscous dissipative effect from fluid for example water or seawater. Note, however, that the bulk dissipation effects are very small in general unless the wave travels a large distance. There may not be much difference after adding MP,VISC for water (or seawater) for relatively short distances. Note that this bulk viscosity term has no effect at FSI locations and does not provide viscous effects at the fluid-solid interface.
