Viscous terms

Does IAMR assume constant viscosity? We are looking at implementing LES models and would like to know if the viscous term is already implemented as del.(mu*del u). That would make things easier.

The default is constant viscosity but you can set ns.variable_vel_visc = 1
in the inputs file to use variable viscosity.
