class FiniteElement from IGESAppli  inherits IGESEntity

        ---Purpose: defines FiniteElement, Type <136> Form <0>
        --          in package IGESAppli
        --          Used to define a finite element with the help of an
        --          element topology.

uses

        Node          from IGESAppli,
        HArray1OfNode from IGESAppli

raises OutOfRange

        ---Purpose : This method is used to set the fields of the class
        --           FiniteElement
        --       - aType    : Indicates the topology type
        --       - allNodes : List of Nodes defining the element
        --       - aName    : Element type name

        Topology (me) returns Integer;
        ---Purpose : returns Topology type

        NbNodes (me) returns Integer;
        ---Purpose : returns the number of nodes defining the element

        Node (me; Index : Integer) returns Node
        raises OutOfRange;
        ---Purpose : returns Node defining element entity
        -- raises exception if Index <= 0 or Index > NbNodes()

        Name (me) returns HAsciiString from TCollection;
        ---Purpose : returns Element Type Name

-- Purpose  : Declaration of variables specific to the definition
--            of the Class FiniteElement.
--
-- Reminder : A FiniteElement instance is defined by :
--            - the topology type
--            - List of Nodes defining the element
--            - Element type name

        theTopology : Integer;
