uses
  MeshElement from SMDS
    
raises 
  ConstructionError   from Standard

is

    	---Purpose: constructor for a tetrahedra

    GetFaceDefinedByNodes(me; rank: Integer; idnode : Address; nb: out Integer) 
    is redefined static;
    ---Purpose: returns the idnodes of the ith face (rank) of the volume
    --          rank must be comprised between 1 and myNbConnections included.
    
    GetEdgeDefinedByNodes(me; rank: Integer; idnode1 : out Integer; idnode2: out Integer) 
    is redefined static;
    ---Purpose: returns the idnodes of the ith edge (rank) of the volume
    --          rank must be comprised between 1 and myNbConnections included.
    

    ComputeKey(me: mutable) is redefined static;
    ---Purpose: compute the  ID of the volume  based on the  id's of its
