+++///  Caution.  Disconnected subnetwork.  During the Y-matrix elimination for phasor voltages, a near-zero diagonal element
                 for node  "XX0002"  exists just prior to reciprocation.    Statistics follow:  Original ABS(Ykk) = 0.00000000E+00,
& A/ E+ S. I4 d: ]$ `1 k                 questionable value = 0.00000000E+00,   tolerance ratio  TOLMAT = 1.00000000E-08  .    The node in question might be
. L) I) d( w4 p                 connected to other nodes, forming a subnetwork, but that subnetwork has no, or only very weak, paths to ground or

                 will now be set to zero, as the solution continues.

这个提示是什么意思。 哪里出问题啦。 谢谢
