The distributed parameter branch card connecting node "XX0032" with node "XX0036" is associated with a propagationmode having a travel time equal to 3.60000000E-09 seconds. But this is less than the time-step size DELTAT, which is illegal.7 R+ J: A* u# w7 \. O6 L' m
Either reduce the step size DELTAT, or replace the distributed modeling by lumped Pi-circuit modeling. 7 c Q7 u" K. z' L# j运行时间不如时间级的deltat,程序非法。请问各位大神如何解决?% B$ T3 x( y( _8 Y& D
