Detailed Description

This class defines a beam with a circular section.

It can be full or hollow, and its radius and thickness can vary from one end of the beam to the other. The valid parameters for circular beams are:

• "R1" or "R": radius at the first end of the beam.
• "R2" or "R": radius at the other end of the beam.
• "EP1" or "EP" (optional): thickness at the first end of the beam. If not specified or equal to 0, the beam is considered full.
• "EP2" or "EP" (optional): thickness at the other end of the beam. If not specified or equal to 0, the beam is considered full.

See class StructuralElementPart for the description of the other parameters.

Member Function Documentation

_makeSectionWires()

def _makeSectionWires (   self,   fPoint,   fNormal,   lPoint,   lNormal  )

private

Create the circular sections used to build the pipe.

References CircularBeam.EP1, CircularBeam.EP2, Beam.filling, CircularBeam.filling, RectangularBeam.filling, Orientation1D.geom, Orientation2D.geom, StructuralElementPart.geom, CircularBeam.R1, and CircularBeam.R2.

_isReversed()

def _isReversed (   self,   path  )

privateinherited

This method checks if a 1D object is "reversed", i.e.

if its orientation is different than the orientation of the underlying OCC object.

References Orientation1D.geom, Orientation2D.geom, and StructuralElementPart.geom.

_getVertexAndTangentOnOrientedWire()

def _getVertexAndTangentOnOrientedWire (   self,   path,   param  )

privateinherited

Get a vertex and the corresponding tangent on a wire by parameter.

This method takes into account the "real" orientation of the wire (i.e. the orientation of the underlying OCC object).

References Beam._isReversed(), Orientation1D.geom, Orientation2D.geom, and StructuralElementPart.geom.

_makeSolidPipeFromWires()

def _makeSolidPipeFromWires (   self,   wire1,   wire2,   point1,   point2,   path  )

privateinherited

Create a solid by the extrusion of section wire1 to section wire2 along path.

References Orientation1D.geom, Orientation2D.geom, and StructuralElementPart.geom.

_buildPart()

def _buildPart (   self )

privateinherited

Build the structural element part.

Reimplemented from StructuralElementPart.

References StructuralElementPart._getSubShapes(), Beam._getVertexAndTangentOnOrientedWire(), CircularBeam._makeSectionWires(), RectangularBeam._makeSectionWires(), and Beam._makeSolidPipeFromWires().

_buildMarkers()

def _buildMarkers (   self )

privateinherited

Build the markers defining the orientation of the structural element part.

Reimplemented from StructuralElementPart.

References StructuralElementPart._getSubShapes(), Beam._getVertexAndTangentOnOrientedWire(), StructuralElementPart._orientation, Beam._orientation, StructuralElementPart2D._orientation, Orientation1D.geom, Orientation2D.geom, and StructuralElementPart.geom.

_getParameter()

def _getParameter (   self,   nameList,   default = None  )

privateinherited

This method finds the value of a parameter in the parameters dictionary.

The argument is a list because some parameters can have several different names.

References StructuralElementPart._parameters, and StructuralElementPart._paramUserName.

_getParamUserName()

def _getParamUserName (   self,   paramName  )

privateinherited

This method finds the user name for a parameter.

References StructuralElementPart._paramUserName.

__repr__()

def __repr__ (   self )

inherited

References InvalidParameterError.groupName, and StructuralElementPart.groupName.

addOrientation()

def addOrientation (   self,   orientParams  )

inherited

Add orientation information to the structural element part.

See class salome.geom.structelem.orientation.Orientation1D for the description of the parameters.

References StructuralElementPart._orientation, Beam._orientation, and StructuralElementPart2D._orientation.

_checkSize()

def _checkSize (   self,   value,   mindim,   expression  )

privateinherited

This method checks that some parameters or some expressions involving those parameters are greater than a minimum value.

References InvalidParameterError.groupName, and StructuralElementPart.groupName.

build()

def build (   self )

inherited

Build the geometric shapes and the markers corresponding to the structural element part in the study.

References StructuralElementPart._buildMarkers(), Beam._buildMarkers(), ThickShell._buildMarkers(), Grid._buildMarkers(), StructuralElementPart._buildPart(), Beam._buildPart(), ThickShell._buildPart(), Grid._buildPart(), and StructuralElementPart.color.

_getSubShapes()

def _getSubShapes (   self,   minDim = MIN_LENGTH_FOR_EXTRUSION  )

privateinherited

Find and return the base sub-shapes in the structural element part.

References StructuralElementPart._groupGeomObj, StructuralElementPart.baseShapesSet, Orientation1D.geom, Orientation2D.geom, StructuralElementPart.geom, InvalidParameterError.groupName, StructuralElementPart.groupName, and StructuralElementPart.isMainShape.
