PythonPointToFieldFunction

class PythonPointToFieldFunction(inputDim, outputMesh, outputDim, func=None)

Override PointToFieldFunction from Python.

Parameters:
inputDimpositive int

Dimension of the input vector d

outputMeshMesh

The output mesh

outputDimpositive int

Dimension of the output field values d’

funca callable python object

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

Examples

>>> import openturns as ot
>>> mesh = ot.RegularGrid(0.0, 0.1, 11)
>>> def  myPyFunc(X):
...     size = 11
...     Y = [ot.Point(X)*i for i in range(size)]
...     return Y
>>> inputDim = 2
>>> outputDim = 2
>>> myFunc = ot.PythonPointToFieldFunction(inputDim, mesh, outputDim, myPyFunc)

Evaluation on a vector:

>>> Yfield = myFunc([1.1, 2.2])
