FunctionGraphMesher

(Source code, svg)

class otmeshing.FunctionGraphMesher(*args)

Function meshing algorithm.

Methods

build(function, outputIndex, minOutput, ...)	Generate a mesh from function discretization.
getClassName()	Accessor to the object's name.
getName()	Accessor to the object's name.
hasName()	Test if the object is named.
setName(name)	Accessor to the object's name.

Examples

>>> import openturns as ot
>>> import otmeshing
>>> bbox = ot.Interval([-8] * 2, [8] * 2)
>>> inputDiscretization = [10] * 2
>>> mesher = otmeshing.FunctionGraphMesher(bbox, inputDiscretization)
>>> f = ot.SymbolicFunction(['x', 'y'], ['cos(x) * sin(y)'])
>>> zIndex = 2  # z axis index
>>> zMin, zMax = 0.01, 0.3  # clip f in [0.01, 0.3]
>>> mesh = mesher.build(f, zIndex, zMin, zMax)

__init__(*args)

build(function, outputIndex, minOutput, maxOutput, outputDiscretization=1, subGraph=True)

Generate a mesh from function discretization.

Parameters:

functionopenturns.Function

Surface function, of output dimension 1

outputIndexint

Index of the output variable

minOutputfloat

Minimum output value

maxOutputfloat

Maximum output value

outputDiscretizationint, optional

Number of discretizations along the output axis (default=1)

subGraphbool, optional

Whether to mesh below or above the surface (default=True: below)

Returns:

meshopenturns.Mesh

The mesh generated.

getClassName()

Accessor to the object’s name.

Returns:

class_namestr

The object class name (object.__class__.__name__).

getName()

Accessor to the object’s name.

Returns:

namestr

The name of the object.

hasName()

Test if the object is named.

Returns:

hasNamebool

True if the name is not empty.

setName(name)

Accessor to the object’s name.

Parameters:

namestr

The name of the object.
