Detailed Description

Defines a Body Fitting 3D algorithm.

It is created by calling smeshBuilder.Mesh.BodyFitted(geom=0)

Constructor & Destructor Documentation

def __init__	(		self,
			mesh,
			geom = 0
	)

Private constructor.

Parameters

mesh	parent mesh object algorithm is assigned to
geom	geometry (shape/sub-shape) algorithm is assigned to; if it is 0 (default), the algorithm is assigned to the main shape

Member Function Documentation

def SetGrid	(		self,
			xGridDef,
			yGridDef,
			zGridDef,
			sizeThreshold = 4.0,
			implEdges = False
	)

Defines "Body Fitting parameters" hypothesis.

Parameters

xGridDef	is definition of the grid along the X asix. It can be in either of two following forms: Explicit coordinates of nodes, e.g. [-1.5, 0.0, 3.1] or range( -100,200,10) Functions f(t) defining grid spacing at each point on grid axis. If there are several functions, they must be accompanied by relative coordinates of points dividing the whole shape into ranges where the functions apply; points coodrinates should vary within (0.0, 1.0) range. Parameter t of the spacing function f(t) varies from 0.0 to 1.0 within a shape range. Examples: "10.5" - defines a grid with a constant spacing [["1", "1+10*t", "11"] [0.1, 0.6]] - defines different spacing in 3 ranges.
yGridDef	defines the grid along the Y asix the same way as xGridDef does.
zGridDef	defines the grid along the Z asix the same way as xGridDef does.
sizeThreshold	(> 1.0) defines a minimal size of a polyhedron so that a polyhedron of size less than hexSize/sizeThreshold is not created.
implEdges	enables implementation of geometrical edges into the mesh.

def SetAxesDirs	(		self,
			xAxis,
			yAxis,
			zAxis
	)

Defines custom directions of axes of the grid.

Parameters

xAxis	either SMESH.DirStruct or a vector, or 3 vector components
yAxis	either SMESH.DirStruct or a vector, or 3 vector components
zAxis	either SMESH.DirStruct or a vector, or 3 vector components

def SetOptimalAxesDirs	(		self,
			isOrthogonal = True
	)

Automatically defines directions of axes of the grid at which a number of generated hexahedra is maximal.

Parameters

isOrthogonal

defines whether the axes mush be orthogonal

def SetFixedPoint	(		self,
			p,
			toUnset = False
	)

Sets/unsets a fixed point.

The algorithm makes a plane of the grid pass through the fixed point in each direction at which the grid is defined by spacing

Parameters

p	coordinates of the fixed point. Either SMESH.PointStruct or a vertex or 3 components of coordinates.
toUnset	defines whether the fixed point is defined or removed.
