aspen dynamics运行显示积分器计算错误？ 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 pQSpec-W-Duty has been reduced from -9.202 GJ/hr to 0.0000 GJ/hr to keep temperature (-214.0 C) within the range -214.0 C to 1995.
