GridDesignOfExperiment

class persalys.GridDesignOfExperiment(*args)

Create a grid design of experiments.

Available constructors:

GridDesignOfExperiment(name, physicalModel)

GridDesignOfExperiment(name, physicalModel, bounds, nbValues, values)

Parameters:

name : str

Name

physicalModel : PhysicalModel

Physical model

bounds : openturns.Interval

Bounds

nbValues : sequence of int

Number of values along each direction

values : sequence of float

Values of the constant variables (optional)

Notes

The sequences must have a dimension equal to the number of inputs in the physical model.

Examples

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

Create the model:

>>> R = persalys.Input('R', 0., ot.LogNormalMuSigma(300., 30., 0.).getDistribution(), 'Yield strength')
>>> F = persalys.Input('F', 0., ot.Normal(75000., 5000.), 'Traction load')
>>> G = persalys.Output('G', 'deviation')
>>> myPhysicalModel = persalys.SymbolicPhysicalModel('myPhysicalModel', [R, F], [G], ['R-F/(pi_*100.0)'])

Create the design of experiments:

>>> myDOE = persalys.GridDesignOfExperiment('myDOE', myPhysicalModel)
