write_file()

Every Package needs its own write_file function

class Mt3dms(modelname='mt3dtest', namefile_ext='nam', modflowmodel=None, ftlfilename='mt3d_link.ftl', ftlfree=False, version='mt3dms', exe_name='mt3dms.exe', structured=True, listunit=16, ftlunit=10, model_ws='.', external_path=None, verbose=False, load=True, silent=0)

Bases: flopy.mbase.BaseModel

MT3DMS Model Class.

Parameters:

• modelname (str, default "mt3dtest") – Name of model. This string will be used to name the MODFLOW input that are created with write_model.
• namefile_ext (str, default "nam") – Extension for the namefile.
• modflowmodel (flopy.modflow.mf.Modflow) – This is a flopy Modflow model object upon which this Mt3dms model is based.
• ftlfilename (str, default "mt3d_link.ftl") – Name of flow-transport link file.
• ftlfree (TYPE, default False) – If flow-link transport file is formatted (True) or unformatted (False, default).
• version (str, default "mt3dms") – Mt3d version. Choose one of: “mt3dms” (default) or “mt3d-usgs”.
• exe_name (str, default "mt3dms.exe") – The name of the executable to use.
• structured (bool, default True) – Specify if model grid is structured (default) or unstructured.
• listunit (int, default 16) – Unit number for the list file.
• ftlunit (int, default 10) – Unit number for flow-transport link file.
• model_ws (str, optional) – Model workspace. Directory name to create model data sets. Default is the present working directory.
• external_path (str, optional) – Location for external files.
• verbose (bool, default False) – Print additional information to the screen.
• load (bool, default True) – Load model.
• silent (int, default 0) – Silent option.

Notes

Examples

>>> import flopy
>>> m = flopy.mt3d.mt.Mt3dms()

get_nrow_ncol_nlay_nper()

classmethod load(f, version='mt3dms', exe_name='mt3dms.exe', verbose=False, model_ws='.', load_only=None, forgive=False, modflowmodel=None)

Load an existing model.

Parameters:

• f (str) – Path to MT3D name file to load.
• version (str, default "mt3dms") – Mt3d version. Choose one of: “mt3dms” (default) or “mt3d-usgs”.
• exe_name (str, default "mt3dms.exe") – The name of the executable to use.
• verbose (bool, default False) – Print information on the load process if True.
• model_ws (str, default ".") – Model workspace path. Default is the current directory.
• load_only (list of str, optional) – Packages to load (e.g. [‘btn’, ‘adv’]). Default None means that all packages will be loaded.
• forgive (bool, default False) – Option to raise exceptions on package load failure, which can be useful for debugging.
• modflowmodel (flopy.modflow.mf.Modflow, optional) – This is a flopy Modflow model object upon which this Mt3dms model is based.

Returns:

Return type:

flopy.mt3d.mt.Mt3dms

Notes

The load method does not retain the name for the MODFLOW-generated FTL file. This can be added manually after the MT3D model has been loaded. The syntax for doing this manually is mt.ftlfilename = 'example.ftl'.

Examples

>>> import flopy
>>> mt = flopy.mt3d.mt.Mt3dms.load('example.nam')
>>> mt.ftlfilename = 'example.ftl'
