WW3 (v6.07.1) Simulation Error – INA2R: ERROR IN READING FROM FILE

[Pbarbosa92]

Hello everyone,

I'm trying to run a WAVEWATCH III (WW3) v6.07.1 simulation, but I keep encountering the following error when executing ww3_grid:

  Equivalent namelists finished.

  The spatial grid:

This simulation was provided by a colleague, and it runs fine on her machine. However, I can't seem to get past this issue on my setup.

I have installed the following dependencies:

• curl (7.64.0)
• zlib (1.2.11)
• HDF5 (1.10.5)
• netCDF-C (4.9.2)
• netCDF-Fortran (4.6.1)

I'm using GCC and GFortran, and below are my nc-config and nf-config outputs:

nf-config --all (netCDF-Fortran 4.6.1)

  --cc        -> gcc  
  --cflags    -> -I/WW3_libs/include -I/WW3_libs/include  
  --fc        -> gfortran  
  --fflags    -> -I/WW3_libs/include -I/WW3_libs/include  
  --flibs     -> -L/WW3_libs/lib -lnetcdff -L/WW3_libs/lib -lnetcdf -lnetcdf -lm  
  --has-f90   ->  
  --has-f03   -> yes  
  --has-nc2   -> yes  
  --has-nc4   -> yes  
  --prefix    -> /WW3_libs  
  --includedir-> /WW3_libs/include  
  --version   -> netCDF-Fortran 4.6.1  

nc-config --all (netCDF 4.9.2)

  --cc            -> gcc  
  --cflags        -> -I/WW3_libs/include -I/WW3_libs/include  
  --libs          -> -L/WW3_libs/lib -lnetcdf  
  --static        -> -lhdf5_hl -lhdf5 -lm -lz -lxml2 -lcurl  
  --has-dap      -> yes  
  --has-nc2      -> yes  
  --has-nc4      -> yes  
  --has-hdf5     -> yes  
  --has-cdf5     -> yes  
  --prefix       -> /WW3_libs  
  --includedir   -> /WW3_libs/include  
  --libdir       -> /WW3_libs/lib  
  --version      -> netCDF 4.9.2  

I'm at a loss as to what could be causing the issue. Any help or suggestions would be greatly appreciated!

Thanks in advance!

Hi,

You cannot run ww3_grid with netcdf input files, you need to create a grid using gridgen to obtain ascii files with WW3 format.

Best,

hi, is this the case for any ww3 version? thank you
