flopy.utils.optionblock module

class OptionBlock(options_line, package, block=True)

Bases: object

Parent class to for option blocks within Modflow-nwt models. This class contains base information and routines that can be shared throughout all option block classes.

Parameters:

• options_line (str) – single line based options string
• package (flopy.pakbase.Package instance) – valid packages include ModflowWel, ModflowSfr2, ModflowUzf1
• block (bool) – flag to write as single line or block type

dtype = 'dtype'

classmethod load_options(options, package)

Loader for the options class. Reads in an options block and uses context from option util dictionaries to check the validity of the data

Parameters:

• options (str or file) – string path to a file or file object
• package (flopy.package type) – valid packages include flopy.modflow.ModflowWel, flopy.modflow.ModflowUzf1, flopy.modflow.ModflowSfr2

Returns:

Return type:

OptionBlock object

single_line_options

Method to get the single line representation of the Options Block

Returns:t Return type:(str) single line representation of Options

update_from_package(pak)

Updater method to check the package and update OptionBlock attribute values based on package values.

Parameters:pak (flopy.package) – valid packages include ModflowWel, ModflowSfr2, and ModflowUzf1 instances

vars = 'vars'

write_options(f)

Method to write the options block or options line to an open file object.

Parameters

f : file, str
