孙兰义老师的example10.4出现问题,各位来给把把脉? 按照孙老师的讲解对孙老师的example10.4-sensity进行实际练习,计算的时候出现下面提示: > Loop $OLVER01 Method: WEGSTEIN Iteration 30 * WARNING(1) CONVERGENCE BLOCK $OLVER01 NOT CONVERGED IN 30 ITERATIONS 5 vars not converged, Max Err/Tol 0.59636E+01 >> Loop $OLVER01 exceeded maximum iterations. ** ERROR(2) Convergence block $OLVER01 did not converge normally in the sensitivity pass on row 8 ** ERROR(3) SOME ROWS COMPLETED WITH ERRORS. ** ERROR(4) BLOCK C IS NOT IN MASS BALANCE: MASS INLET FLOW = 0.15530727E+03, MASS OUTLET FLOW = 0.15522085E+03 RELATIVE DIFFERENCE = 0.55675427E-03 MAY BE DUE TO A TEAR STREAM OR A STREAM FLOW MAY HAVE BEEN CHANGED BY A FORTRAN, TRANSFER, OR BALANCE BLOCK AFTER THE BLOCK HAD BEEN EXECUTED. ** ERROR(5) Convergence block $OLVER01 did not converge normally in the final pass ->Simulation calculations completed ... ->Generating results ... 从上面看有五处error,第一个是在30步的收敛过程中不收敛,我尝试对”C“block的interaction进行修改,30改成100还是未解决问题。 第二、三、五个error不是很清楚。第四个error是物料不平衡,由于C block的inlet和outlet不需要手动输入,不知道该如何下手进行修改。 虽然我有孙兰义老师example10.4-sensity.bkp文件,但我使用的 aspen plus版本较低无法查看,我将我自己做的上传,希望哪位能给出具体的修改方法,非常非常感谢 查看更多2个回答 . 1人已关注
