哪位高手帮忙看看:我将aspen稳态文件导入到动态后,初始化顺利通过,但是运行的时候显示如下错误,最后弹出一个提示框:integrator corrector failed……在simulation messages中的信息如下:
Step 1: Time = 0.001, step = 0.001 accepted (at min), error/tol = 6.7646
Step 2: Time = 0.002, step = 0.001 accepted (at min), error/tol = 2.3118
Step 3: Time = 0.003, step = 0.001 accepted (at min), error/tol = 1.4171
Step 4: Time = 0.004, step = 0.001 accepted (at min), error/tol = 1.3844
Step 5: Time = 0.005, step = 0.001 accepted (at min), error/tol = 2.1978
Step 6: Time = 0.006, step = 0.001 accepted (at min), error/tol = 4.1074
Step 7: Time = 0.007, step = 0.001 accepted (at min), error/tol = 7.7738
Step 8: Time = 0.008, step = 0.001 accepted (at min), error/tol = 14.675
Step 9: Time = 0.009, step = 0.001 accepted (at min), error/tol = 28.567

好像说塔1的冷凝器出了问题,但具体看不懂,稳态里面运行的很好呀,实在解决不了,还请大家帮忙看看,感激不尽!
