aspen plus 中的设计规定问题? 我用aspen plus 做了一个 甲醇 加压塔的模拟,已知塔顶甲醇的浓度,想通过用设计规定的方式整定出实际塔板效率是多少!不知道为什么总是出错啊,算不出结果来!改用灵敏度分析算,还是不行! 在选择操作变量时我选的是tray efficiency, 后来又改成了 stage efficiency.都只显示错误,算不出结果。显示错误如下: ** ERROR WHILE CHECKING INPUT SPECIFICATIONS FOR VARIED VARIABLE IN DESIGN-SPEC: "JJTTBXL" NO "STAGE-EFF" SENTENCE WAS ENTERED IN THE REFERENCED PARAGRAPH. VARIABLE DEFINITION IGNORED. *** SEVERE ERROR IN THE "DESIGN-SPEC" PARAGRAPH WHICH BEGINS ON LINE 130 SPEC NAME: JJTTBXL NO VARY SENTENCE WAS ENTERED FOR THIS PARAGRAPH. ** ERROR IN THE "DESIGN-SPEC" PARAGRAPH WHICH BEGINS ON LINE 130 SPEC NAME: JJTTBXL DUE TO PREVIOUS ERRORS DESIGN SPEC JJTTBXL WILL BE IGNORED ** ERROR WHILE CHECKING INPUT SPECIFICATIONS FOR VARIED VARIABLE IN SENSITIVITY BLOCK: "JJTJCJD" NO "STAGE-EFF" SENTENCE WAS ENTERED IN THE REFERENCED PARAGRAPH. VARIABLE DEFINITION IGNORED. ! Errors while processing input specifications 还请各位高手多多指教啊!!!谢谢!!查看更多2个回答 . 1人已关注
