LinearInterpolation

class fridom.framework.grid.cartesian.linear_interpolation.LinearInterpolation

Bases: InterpolationModule

Simple linear interpolation for cartesian grids.

\[f(x + 0.5 \Delta x) = \frac{1}{2} (f(x) + f(x + \Delta x))\]

Methods

__init__()
disable()	Enabling the module means that it will be executed at each time step.
enable()	Enabling the module means that it will be executed at each time step.
interpolate(f, destination)	Interpolate the field to the destination position.
interpolate_axis(f, axis, destination)
is_enabled()	Return whether the module is enabled or not.
reset()	Stop and start the module.
setup(mset)	Start the module
start()	Start the module
stop()	Stop the module
update(mz)	Update the module

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.

name = 'Linear Interpolation'

setup(mset: ModelSettingsBase) → None

Start the module

Description

This method is called by the ModelSettings.setup() and sets the ModelSettings as well as the differentiation and interpolation modules.

interpolate(f: FieldVariable, destination: Position) → FieldVariable

Interpolate the field to the destination position.

Parameters

ffr.FieldVariable

The field to interpolate.

destinationfr.grid.Position

The position to interpolate to.

Returns

fr.FieldVariable

The interpolated field.

interpolate_axis(f: FieldVariable, axis: int, destination: AxisPosition) → FieldVariable
