OpenTURNSPythonFieldFunction

class OpenTURNSPythonFieldFunction(inputMesh, inputDim, outputMesh, outputDim)

Override FieldFunction from Python.

Parameters:

inputMeshMesh

The input mesh

inputDimint,

Dimension of the values of the input field

outputMeshMesh

The output mesh

outputDimint,

Dimension of the values of the output field

Methods

getInputDescription
getInputDimension
getInputMesh
getOutputDescription
getOutputDimension
getOutputMesh
setInputDescription
setOutputDescription

Notes

You have to overload the function:

_exec(X): single evaluation, X is a Field, returns a Field

Examples

>>> import openturns as ot
>>> mesh = ot.Mesh(1)
>>> class FUNC(ot.OpenTURNSPythonFieldFunction):
...     def __init__(self):
...         # first argument:
...         super(FUNC, self).__init__(mesh, 2, mesh, 2)
...         self.setInputDescription(['R', 'S'])
...         self.setOutputDescription(['T', 'U'])
...     def _exec(self, X):
...         Y = ot.Field(self.getOutputMesh(), X.getValues() * ([2.0]*X.getValues().getDimension()))
...         return Y
>>> F = FUNC()

Create the associated FieldFunction:

>>> myFunc = ot.FieldFunction(F)

__init__(inputMesh, inputDim, outputMesh, outputDim)
