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. $ g! y. Q4 }; e' h" TEither reduce the step size DELTAT, or replace the distributed modeling by lumped Pi-circuit modeling. - ~# H% r. ]3 p4 C" G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?7 _, i5 v* d1 X2 k/ M2 e" v1 Z
