WW3 nest boundary conditions not working for ww3 v6.07 #997

Originally posted by **JMSnyder1980** April 22, 2023 I am trying to run ww3 6.07 for the globe and then a nest covering the area around the Mediterranean Sea region with boundary conditions. The global run works fine with boundary conditions and these boundary conditions appear to be shown in the ww3_grid for the Mediterranean region. Unfortunately when I run the ww3 model for the Mediterranean Sea region I get the following error message: [medplus_error.log](https://github.com/NOAA-EMC/WW3/files/11302780/medplus_error.log) When I run the model with using NONE in the ww3_grid.inp instead of SMPL it works fine but I get excluded points along the boundaries of the global and Mediterranean Sea nests which I do not want especially in the global run since I do not have values around 179 or 180 degrees longtitude. Attached are the ww3_grid.inp, ww3_prep.inp and ww3_shel.inp for the global run: [ww3_grid.inp_global.txt](https://github.com/NOAA-EMC/WW3/files/11302790/ww3_grid.inp_global.txt) [ww3_shel.inp_global.txt](https://github.com/NOAA-EMC/WW3/files/11302791/ww3_shel.inp_global.txt) [ww3_prep.inp_global.txt](https://github.com/NOAA-EMC/WW3/files/11302792/ww3_prep.inp_global.txt) [ww3_grid.nml_global.txt](https://github.com/NOAA-EMC/WW3/files/11302801/ww3_grid.nml_global.txt) and the ww3_grid.inp ww3_prep.inp and ww3_shel.inp for the Mediterranean Sea Run: [ww3_grid.nml_medplus.txt](https://github.com/NOAA-EMC/WW3/files/11302795/ww3_grid.nml_medplus.txt) [ww3_shel.inp_medplus.txt](https://github.com/NOAA-EMC/WW3/files/11302797/ww3_shel.inp_medplus.txt) [ww3_prep.inp_medplus.txt](https://github.com/NOAA-EMC/WW3/files/11302798/ww3_prep.inp_medplus.txt) [ww3_grid.inp_medplus.txt](https://github.com/NOAA-EMC/WW3/files/11302838/ww3_grid.inp_medplus.txt) Also attached are the bathemetry and obstruction grid files for global and Mediterranean Sea Regions: [medplus_0p25_obst.dat.txt](https://github.com/NOAA-EMC/WW3/files/11302805/medplus_0p25_obst.dat.txt) [medplus_0p25_bathy.dat.txt](https://github.com/NOAA-EMC/WW3/files/11302806/medplus_0p25_bathy.dat.txt) [global_1p00_obst.dat.txt](https://github.com/NOAA-EMC/WW3/files/11302807/global_1p00_obst.dat.txt) [global_1p00_bathy.dat.txt](https://github.com/NOAA-EMC/WW3/files/11302808/global_1p00_bathy.dat.txt) Also I have a sample wind file: [globalwinds.dat.txt](https://github.com/NOAA-EMC/WW3/files/11302821/globalwinds.dat.txt) and the namelist.nml file for both Mediterranean sea and Global runs: [namelists.nml.txt](https://github.com/NOAA-EMC/WW3/files/11302840/namelists.nml.txt) Can you advise on how to tweak the input files for the Mediterranean Sea run and the Global run to have this work where I can successfully pass boundary conditions from the Global run to the Mediterranean Sea run?

Hello, did you solve this problem? I have the same problem as you. I think it's a problem with small nested boundary settings. How did you solve it?
