pytuflow.DAT#

class DAT(fpath, twodm=None)#

Bases: Mesh

Class for handling DAT mesh file.

Parameters:

  • fpath (PathLike or list[PathLike]) – Path to the DAT file, list of DAT files, or a SUP file.

  • twodm (PathLike, optional) – Path to the 2dm file. If not provided, the class will attempt to find the 2dm file with the same name as the DAT file. If an SUP file is provided in the first argument, the 2dm argument is not used.

Examples

>>> from pytuflow import DAT
>>> dat = DAT('./path/to/dat.ALL.sup')

Get all the data types available in the DAT results:

>>> dat.data_types()
['bed level', 'depth', 'vector velocity', 'velocity', 'water level']

Get all the data types that have maximum values:

>>> dat.data_types('max')
['depth', 'velocity', 'water level']

Get all the available times in the DAT results:

>>> dat.times()
[0.0, 0.016666666666666666, ..., 3.0]

Get the available times for the depth data type:

>>> dat.times('depth')
[0.0, 0.016666666666666666, ..., 3.0]

Get the water level time-series data for a given point defined as (x, y):

>>> dat.time_series((293250, 6178030), 'water level')
        time  pnt1/water level
