    I have added a library of Tube to Orcad 10.3.
    I have runned simulation of a my circuit that contain a part of tube library
    and I have error undefined subcircuit.

    I have added the library as global and now I have errors of node floating.

    How i can do ?

    Well, supply a schematic (pretty hard to help without that)

    Have you add the "0" ground sysmbol?

    P Spice needs a DC connection to every node,....

    node floating usually means lack of a DC connection...

    connect a 100Meg resistor form the floating node to ground just to make
    Pspice happy.

    If 100 Mrg will effect your circuit use 1000Meg or whatever it takes
    not to impact your circuit but make Pspice happy.

    I have solved the problem connecting the 0 volt ground.
