CST CS與MWS聯合仿真TRANSIENT仿真

CST2009中
我想用Transient仿真加Probe看一路接地電容的端的電壓情況，濾波器的工作頻率為30MHz
但是,我設置time end=2000ns時，仿真報錯
Accuracy of passivated MOR is insufficient
Calculating impluse response of block MWSSCHEM1 by IFT
instability. Restart transient task with different time step settings
Instability. Restart transient task with different time integration method.
Instability in transient simulation
simulated failed
設置time end=1000ns不報錯
但是結果很離譜，求大神們指點

上傳CST文件吧

還請大神把把脈CST2009

壓縮包只有一個，兩個是一樣的，麻煩您看一下，電路聯合瞬態仿真存在的問題還請您幫忙分析一下
