Problem about the windrot

[Caizhiwen19901122]

When I try to obtain the windrot_geo2proj.gr3 file, an error occurs as: TypeError: init() missing 1 required positional argument: 'nodes'

The code is: from datetime import datetime from time import time import pathlib

from pyschism.forcing.nws.nws2.era5 import ERA5 from pyschism.forcing.nws.nws2.nws2 import NWS2

from pyschism.mesh.hgrid import Hgrid from pyschism.mesh.gridgr3 import Windrot from pyschism.mesh.base import Gr3

if name == 'main':

startdate=datetime(2018, 1, 1)
rnday=5

t0=time()
hgrid = Gr3.open('./hgrid.gr3', crs='epsg:4326')
bbox = hgrid.get_bbox('EPSG:4326', output_type='bbox')
windrot=Windrot().default(hgrid=Hgrid)

@Caizhiwen19901122 when you want to create the wind rotation object from the grid, you should call it like

hgrid = Hgrid.open('./hgrid.gr3', crs='epsg:4326')
windrot = Windrot.default(hgrid=hgrid)

Note that:

• there are no parentheses immediately after Windrot
• you need to pass the hgrid object to the default method, and not the Hgrid class.
• I'm using Hgrid class to open the grid file. Hgrid is a class that inherits Gr3 class and has boundary definition capability too
