From @uturuncoglu,

git clone -b feature/schism_3d --recursive https://github.com/oceanmodeling/ufs-weather-model.git
cd ufs-weather-model/tests
./compile.sh "hercules" "-DAPP=CSTLSW -DUSE_ATMOS=ON -DUSE_WW3=ON -DNO_PARMETIS=OFF -DOLDIO=ON -DPDLIB_BT4=ON" coastal intel 0 0

This will create an executable under tests/ directory called as fv3_coastal.exeto test. To ingest surface elevation from WW3, Add input%forcing%water_levels = 'C' option to WW3 namelist file. SCHSIM will automatically write incoming wave related fields to its own history. In SCHSIM side, and Add RADFLAG = 'VOR'.

The configuration for the coarse resolution SCHISM mesh is located at /work2/noaa/nosofs/yunfangs/hurricane_ian/atm_sch_ww3_new/coastal_ian_crs_atm2sch2ww3_intel_test4_1_h_exchange_template

The configuration with wave boundary is located at

It seems that adding the water level exchange in the schism and ww3 coupled model contribute little to the water level simulation for the coarse mesh.

From the comparisons, the coupled WW3 cases with water level exchange have lower Hs than without ones.
