FieldMonteCarloAnalysis¶

class persalys.FieldMonteCarloAnalysis(*args)¶

Run a Monte Carlo analysis for models with mesh.

Parameters

namestr: Name
modelPhysicalModel: Model containing a mesh

Examples

>>> import openturns as ot
>>> import persalys

Create the model:

>>> meshModel = persalys.GridMeshModel(ot.Interval(0., 12.), [5])

>>> z0 = persalys.Input('z0', 100, ot.Uniform(100, 150))
>>> v0 = persalys.Input('v0', 55, ot.Normal(55, 10))
>>> m = persalys.Input('m', 80, ot.Normal(80, 8))
>>> c = persalys.Input('c', 15, ot.Uniform(0, 30))
>>> z = persalys.Output('z', '')
>>> formula = ['max(0, z0 + (m * 9.81 / c) * t + (m / c) * (v0 - (m * 9.81 / c)) * (1 - exp(-t * c / m)))']

>>> model = persalys.SymbolicFieldModel('aModel', meshModel, [z0, v0, m, c], [z], formula)

Create the analysis:

>>> analysis = persalys.FieldMonteCarloAnalysis('analysis', model)
>>> analysis.setMaximumCalls(30)
>>> analysis.run()

Get the result:

>>> result = analysis.getResult()
