BiharmonicClosure

class fridom.nonhydro.modules.closures.biharmonic_closure.BiharmonicClosure(kh: float, kv: float, velocity_scale: float = 1.0)

Bases: Module

Biharmonic friction + mixing for the nonhydrostatic model.

Parameters

khfloat

horizontal diffusion coefficient

kvfloat

vertical diffusion coefficient

__init__(kh: float, kv: float, velocity_scale: float = 1.0) → None

Methods

__init__(kh, kv[, velocity_scale])
disable()	Disable the module.
enable()	Enable the module.
is_enabled()	Whether the module is enabled or not.
reset()	Stop and start the module.
setup(mset[, setup_mode])	Set the module up.
start()	Start the module.
stop()	Stop the module.
update(mz)	Update the model state.

Attributes

diff_module	The differentiation module to be used by this module.
grid	The grid of the model settings.
info	Return a dictionary with information about the time stepper.
interp_module	The interpolation module to be used by this module.
is_setup	Whether the module is set up.
mset	The model settings.
name
required_halo	The required halo points for this module.

name = 'Biharmonic Closure'

update(mz: ModelState) → ModelState

Update the model state.

Description

This method is called by the model at each time step. Child classes should overwrite this method to update the module. Make sure to decorate the method with the @module_method decorator.

Parameters

mzfr.ModelState

The model state at the current time step.

Returns

fr.ModelState

The updated model state.
