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. : j4 ~2 j, j% I+ R. SEither reduce the step size DELTAT, or replace the distributed modeling by lumped Pi-circuit modeling. ; |9 T3 q) u4 O" _2 b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? / A9 Z+ s6 I7 i8 S/ B; Q- k8 g
