Simulation started at Time = 0 using integration method Dassl

Warning:Time = 154.0760451, the nonlinear system (1, 1) failed!
Warning:Time = 154.0760425, the nonlinear system (1, 1) failed!
Warning:Time = 154.0760426, the nonlinear system (1, 1) failed!
Warning:Time = 154.0760418, the nonlinear system (2, 2) failed!
Warning:Time = 154.0760418, the nonlinear system (2, 2) failed!
Warning:Time = 154.0760418, the nonlinear system (2, 2) failed!
Warning:Time = 154.0760418, the nonlinear system (2, 2) failed!
Warning:Time = 154.0760418, the nonlinear system (2, 2) failed!
Warning:Dassl couldn't handle this failure, and try to restart!
Error:Integrator Dassl stepping forward failed:target time was 154.2, but actual time reached was 154.076.

您好,可以在【仿真设置-调试】中勾选 “非线性求解结果”、“非线性统计信息”和“非线性迭代过程” ,再次运行仿真,查看【输出面板】的信息。在输出的末尾部分,会明确指出哪些组件的哪些变量存在问题,导致了非线性迭代的失败。
