Dymola模拟日志中有哪些(U)事件

Question

运行Dymola模型时，会在模拟日志中生成下表:集成在T=4时成功终止

CPU-time for integration      : 0.002 seconds 

CPU-time for one GRID interval: 0.2 milli-seconds 

 Number of result points       : 11 

Number of GRID   points       : 11 

Number of (successful) steps  : 227 

Number of F-evaluations       : 785 

Number of H-evaluations       : 261 

Number of Jacobian-evaluations: 68 

Number of (model) time events : 4 

Number of (U) time events     : 0 

Number of state    events     : 2 

Number of step     events     : 0 

Minimum integration stepsize  : 3.24e-005 

Maximum integration stepsize  : 0.317 

Maximum integration order     : 5

“(U)个时间事件数”是什么意思？

Answer 1

弄清楚了：(U)在使用dsu.txt时会发生时间事件，并且在dsu.txt中也有事件。
