ASPEN PLUS转DYNAMICS前水力学计算设置问题？ 提示模块之间有压差，应该增加变压模块，但是教程上下一步的流程图上看，并没有变压模块被加入。 而且发现，选择file-sendto-flow driven dyn simulation 的时候出现如下错误提示，不明白这个压差到底该怎么设，静态的时候设置的top 20bar / stage 2 20.1bar / pressure drop for rest of column 0.01bar translate using compiled ast procedures in d:\program files\aspentech\aspen dynamics 2006.5\ast directory. translating block t101 of type radfrac: the specified pressure drops in the column are smaller than the liquid head on the stages listed below. please adjust the pressure profile on the pressure sheet of the setup form. a typical total pressure drop across a stage is twice the pressure drop due to liquid head. alternatively, modify the weir heights or column diameter on these stages. if you are modelling a packed column, select the simple packing option on the hydraulics sheet of the dynamics form. if you are using tray-rating or packing-rating, ensure your input parameters are consistent. p_dropl = pressure drop due to liquid head on stage (bar). p_drop = total pressure drop on stage (bar). stage p_dropl (bar) p_drop (bar) 2 3.707169482797e-003 2.516399999998e-003 3 3.704684250114e-003 2.516800000002e-003 4 3.705284304499e-003 2.519400000001e-003 5 3.709017019805e-003 2.524200000000e-003 6 3.715298915066e-003 2.530499999999e-003 7 3.723060821953e-003 2.537600000000e-003 8 3.730845629100e-003 2.544000000000e-003 9 3.737512588792e-003 2.549399999999e-003 10 3.742604562771e-003 2.553299999999e-003 11 3.746119068066e-003 2.556000000002e-003 12 3.748334193373e-003 2.557699999997e-003 13 5.879022101302e-003 3.288300000001e-003 14 5.884331203934e-003 3.285699999999e-003 15 5.906617090782e-003 3.296500000001e-003 16 5.955293725095e-003 3.321000000000e-003 17 6.033883852505e-003 3.363100000001e-003 18 6.144457533351e-003 3.347899999998e-003 19 6.242343937881e-003 3.404500000002e-003 20 6.311770922067e-003 3.449300000000e-003 fatal error: please correct the errors above before continuing aborting procedure d:\program files\aspentech\aspen dynamics 2006.5\ast\radfrac.tbl查看更多
