Detailed Description

class for holding information about a finite element.

NAME: DynElement - class for holding information about a finite element

DESCRIPTION:

The class implements a finite element. That is, the class stores all the relevant information on one finite element. In detail the class contains: a "VecSimplest" containing the nodes in the element, number of nodes in the element, the element type, the elements material number and the elements global centroid. The last variable, "is_outside", determines whether the element centroid is outside a user given domain or not. The variable is used in "removeDomainExtended", "triangularElement" and "twoTriangularElements" in "GridDynFE". Each element is included in the element list in "GridDynFE". The public "HandleId" ensures that handles can be used on the class. The friend class "DpList" ensures that the element can be included in a element list in class "GridDynFE".

Constructor & Destructor Documentation

DynElement::DynElement ( int elm_no,

const GridFE & grid,

const VecSimplest(Handle(DynNode)) & node_vec )

There are three constructors. One empty constructor and one that takes the element number, a "GridFE" object and a "VecSimplest" containing "Handle" pointers to the elements nodes as argument. The third constructor takes the number of nodes, the element type, the global centroid, the material number and three handles pointing to three nodes as argument, and constructs a triangular element.

DynElement::DynElement ( int nne_,

const String & elm_tp_,

const Ptv(real) & global_centroid_,

int material_no_,

const Handle(DynNode) & node1,

const Handle(DynNode) & node2,

const Handle(DynNode) & node3 )

See documentation of one of the overloaded constructor.

Member Function Documentation

const String & DynElement::getElmType ( ) const

returns the element type.

const Ptv(real) & DynElement::getGlobalCentroid ( ) const

returns the coordinates of the global centroid.

void DynElement::getLocNodeVec ( VecSimplest(Handle(DynNode)) & l_n_vec ) const

assigns the local node vector given as argument to the elements local node vector.

int DynElement::getMaterialType ( ) const

returns the material number of the element.

int DynElement::getNoNodesInElm ( ) const

returns the number of nodes in the element.

bool DynElement::operator!= ( const DynElement & element ) const

tests for equality by comparing the global centroids. The function is called for by the "DpList" class.

bool DynElement::operator< ( const DynElement & element ) const

compares two elements and returns "true" if this element has smaller global centroid than the element given as argument. This function is required by the "sort" function in the element list. The element with the smallest global centroid coordinates is the element which is nearest the origin.

DynElement & DynElement::operator= ( const DynElement & element )

assigns this element to the element given as argument.

bool DynElement::operator== ( const DynElement & element ) const

uses "operator!=" to determine whether the element given as argument and this element are alike or not. Returns "true" if they are, and "false" if not.

void DynElement::print ( Os & os )

print the contents of the element to the output given as argument. Mainly for debugging purposes.

void DynElement::replaceNode ( int local_node,

DynNode & new_node )

given a local node number "local_node", the node handle of this local node is rebound to a new node ("new_node").

void DynElement::setElmType ( const String & type )

sets the element type to the element type given as argument.

void DynElement::setLocNodeVec ( const VecSimplest(Handle(DynNode)) & l_n_vec )

sets the local node vector.

void DynElement::setNoNodesInElm ( int number_of_nodes_in_elm )

sets number of nodes in the element.

class ManipGridDynFE [friend]

Os & operator<< ( Os & os,

DynElement & element ) [friend]

calls the print function. The function is called for by the "DpList" class.
