    I am trying to perform a cirucit simulation with a switch in the cirucit. The switch has been close for a long time before being opened at t = 0s.
    When I run the simulation I get the following error:



    **** INCLUDING SCHEMATIC1.net ****
    * source PSPICE AGAIN
    R_R1 N01660 N01684 15
    R_R2 N01684 N02322 50

    + Ropen=0ms

    **** RESUMING "spice run again .cir" ****
    .END

    ERROR -- Subcircuit Sw_tOpen used by X_U1 is undefined


    PLEASE HELP ME OUT!
