ImportedMeshModel

class persalys.ImportedMeshModel(*args)

Create a model with imported meshes

Available constructors:

ImportedMeshModel(parameters, fileName, columns)

Parameters:

parameterssequence of persalys.Variable

Sequence of index parameters (optional). By default the index parameter is named t

fileNamestr

Name of a data file to load

columnssequence of int

Indices of columns in files to consider. The sequence dimension must have a dimension equal to the number of index parameters

Methods

getBounds()	Get bounds of the mesh nodes accessor.

Examples

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

Create the mesh model:

>>> mesh = ot.IntervalMesher(ot.Indices(1, 20)).build(ot.Interval(0., 12.))
>>> mesh.getVertices().exportToCSVFile('mesh.csv')

>>> meshModel = persalys.ImportedMeshModel([persalys.Variable('x', 'aDescription')], 'mesh.csv', [0])

Create the model:

>>> z0 = persalys.Input('z0', 100)
>>> v0 = persalys.Input('v0', 55)
>>> m = persalys.Input('m', 80)
>>> c = persalys.Input('c', 15)
>>> z = persalys.Output('z')
>>> formula = ['max(0, z0 + (m * 9.81 / c) * x + (m / c) * (v0 - (m * 9.81 / c)) * (1 - exp(-x * c / m)))']
>>> model = persalys.SymbolicFieldModel('model', meshModel , [z0, v0, m, c], [z], formula)

>>> y = model.getPointToFieldFunction()([100, 55, 80, 15])
