PythonFieldFunction

class PythonFieldFunction(*args)

Override FieldFunction from Python.

Parameters:
inputDim : int, \geq 1

Dimension d of the values of the input field

outputDim : int, \geq 1

Dimension d' of the values of the output field

spatialDim : int, \geq 1

Dimension n of the domain \cD

func : a callable python object

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

Examples

>>> import openturns as ot
>>> 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
>>> spatialDim = 1
>>> myFunc = ot.PythonFieldFunction(inputDim, outputDim, spatialDim, myPyFunc)
