Xarray extension to work with 2D unstructured grids, for data and topology stored according to UGRID conventions.

Processing structured data with xarray is convenient and efficient. The goal of Xugrid is to extend this ease to unstructured grids.

import matplotlib.pyplot as plt
import xugrid

# Get some sample data as a xugrid UgridDataArray
uda = xugrid.data.elevation_nl()

# Get a cross-section
section_y = 475_000.0
section = uda.ugrid.sel(y=section_y)

# Plot unstructured grid and cross section
fig, (ax0, ax1) = plt.subplots(figsize=(22.6, 10), ncols=2)
uda.ugrid.plot(ax=ax0, vmin=-20, vmax=90, cmap="terrain")
ax0.axhline(y=section_y, color="red")
section.plot(ax=ax1, x="mesh2d_face_x")
