PythonFieldFunction

class PythonFieldFunction(*args)

Override FieldFunction from Python.

Parameters:
inputMesh : Mesh

The input mesh

inputDim : int, \geq 1

Dimension d of the values of the input field

outputMesh : Mesh

The output mesh

outputDim : int, \geq 1

Dimension d' of the values of the output field

func : a callable python object

called on a Field object. Returns a Field. Default is None.

Examples

>>> import openturns as ot
>>> mesh = ot.Mesh(1)
>>> def myPyFunc(X):
...     mesh = X.getMesh()
...     values = X.getValues() * ([2.0]*X.getValues().getDimension())
...     values.setDescription(ot.Description.BuildDefault(values.getDimension(), 'Y'))
...     Y = ot.Field(mesh, values)
...     return Y
>>> inputDim = 2
>>> outputDim = 2
>>> myFunc = ot.PythonFieldFunction(mesh, inputDim, mesh, outputDim, myPyFunc)

Returns:
class_name : str

The object class name (object.__class__.__name__).

getId()

Accessor to the object’s id.

Returns:
id : int

Internal unique identifier.

getImplementation(*args)

Returns:
d : int

Dimension d of the input field values.

getInputMesh()

Get the mesh associated to the input domain.

Returns:
inputMesh : Mesh

The input mesh \cM_{N'}.

getMarginal(*args)

Get the marginal(s) at given indice(s).

Parameters:
i : int or list of ints, 0 \leq i < d'

Indice(s) of the marginal(s) to be extracted.

Returns:
fieldFunction : FieldFunction
