imod.util.empty_3d_transient(dx: float | ndarray[Any, dtype[floating]], xmin: float, xmax: float, dy: float | ndarray[Any, dtype[floating]], ymin: float, ymax: float, layer: int | Sequence[int] | ndarray[Any, dtype[int64]], time: Any) → DataArray[source]#

Create an empty transient 3D (time, layer, x, y) DataArray.

dx and dy may be provided as:

  • scalar: for equidistant spacing

  • array: for non-equidistant spacing

Note that xarray (and netCDF4) uses midpoint coordinates. xmin and xmax are used to generate the appropriate midpoints.

Parameters:

  • dx (float, 1d array of floats) – cell size along x

  • xmin (float)

  • xmax (float)

  • dy (float, 1d array of floats) – cell size along y

  • ymin (float)

  • ymax (float)

  • layer (int, sequence of integers, 1d array of integers)

  • time (Any) – One or more of: str, numpy datetime64, pandas Timestamp

Returns:

empty – Filled with NaN.

Return type:

xr.DataArray
