Leeway's error: The truth value of an array with more than one element is ambiguous. Use a.amy() or a.all() #441

I use my own forcast files from rooms ang wrf. When I run the leeway model, there are errors as follows: read_netCDF_CF_generic.py, line 317, ininit if rel_delte > 0.05 and The truth value of an array with more than one element is ambiguous. Use a.amy() or a.all()

knutfrode commented 3 years ago

There seem to be some problem with your input files, either ROMS or WRF. Are these CF-compatible, with constant delta_x and delta_y for the coordinates? Can you post an ncdump of the forcing file which produces the error?

I have upload the wind and current files.

In your WRF-files the variables x and y claim to contain projection coordinates, however these are empty.

I can read your files after removing these variables from the file with ncks -x -v x,y WRF_TaiWanZhouBian_2020082100_t001.nc out.nc

After this, variables longitude and latitude are used instead of x and y.
