v3.4.0

Features:

• Meso-micro coupling with no precursor for terrain
• Anelastic implementation defines and uses reference temperature field
• Coupling to OpenFAST 4.0 enabled, compile time option
• Underwater current enabled for linear waves, numerical beach
• Underwater terrain forcing (bathymetry) enabled through changes to ocean waves forcing and boundary conditions
• Ocean waves can be represented as moving terrain using immersed forcing
• Change to multiphase hybrid coupling – both projections
