用ASPEN做化学链模拟，不知道该怎么解决这个计算突然止 ...？ 各位前辈，谢谢你的关注！ 我是一个刚刚接触ASPEN的孩子 ，想用Aspen来模拟生物质化学链气化的循环过程，中间用 氧化铁 来与生物质反应，想着用RGIBBS来模拟气化 反应器 ，最后画了附件中的流程图，我知道有很多数据可能都没有输入，但是遇到这个计算突然停止的问题，不知道怎么解决，因为之前看文献都说用PR-BM物性方法，希望前辈看看文件，给个提示，谢谢。 << Loading Simulation Engine 15:21:06 Tue May 2, 2017>> ->Processing input specifications ... * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER TC/ELEMENT 1 (DATA SET 1) UPPER BOUND VIOLATED FOR COMPONENT FE VALUE = 9340.0 , UPPER BOUND = 7000.0 * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER PC/ELEMENT 1 (DATA SET 1) UPPER BOUND VIOLATED FOR COMPONENT C VALUE = 0.22300E+09, UPPER BOUND = 0.10000E+09 * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER PC/ELEMENT 1 (DATA SET 1) UPPER BOUND VIOLATED FOR COMPONENT FE VALUE = 0.10150E+10, UPPER BOUND = 0.10000E+09 * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER SG/ELEMENT 1 (DATA SET 1) UPPER BOUND VIOLATED FOR COMPONENT FE VALUE = 8.3164 , UPPER BOUND = 4.0000 * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER API/ELEMENT 1 (DATA SET 1) LOWER BOUND VIOLATED FOR COMPONENT FE VALUE = -114.48 , LOWER BOUND = -110.00 * WARNING IN PHYSICAL PROPERTY SYSTEM PARAMETER FREEZEPT/ELEMENT 1 (DATA SET 1) UPPER BOUND VIOLATED FOR COMPONENT C VALUE = 4300.0 , UPPER BOUND = 4000.0 Flowsheet Analysis : Block $OLVER01 (Method: NEWTON ) has been defined to converge streams: $HRSGQ02 $HRSGQ03 $HRSGQ04 FE2O3 COMPUTATION ORDER FOR THE FLOWSHEET: DECOMP DECOM PUMP $OLVER01 $HRSGHTR FSTEAM GR SR AR CYCLONE1 TB1 $HRSGH04 | $HRSGH02 CYCLONE2 TB2 $HRSGH03 (RETURN $OLVER01) ->Calculations begin ...
