新手Aspenplus使用RCSTR模拟出错（恳请赐教）？ 下面是运行日志，请各位大侠赐教，附件中有bkp文件 - rocessing input specifications ... information binary parameters prkij (data set 1) for model esprstd are retrieved from sdf table. table name = esprstd flowsheet analysis : block $olver01 (method: secant ) has been defined to converge specs : ds-1 computation order for the flowsheet: $olver01 cstr (return $olver01)- calculations begin ... block: cstr model: rcstr ** error m-bal loop did not converge in 50 iterations. check stoichiometry/molecular weights. * warning at inner loop iteration number 50 : reaction rate is greater than zero for reaction (1) but reactant "h3n" is not present. possible cause: zeroth order reactant not present. rate is set to zero. beginning convergence loop $olver01 method: secant * warning initial value for design spec variable 1 is at or above upper bound. value = 0.194444e-02 lower bound = 0.251996e-03 upper bound = 0.125998e-02 variable reset to 0.115918e-02 block: cstr model: rcstr ** error m-bal loop did not converge in 50 iterations. check stoichiometry/molecular weights. loop $olver01 method: secant iteration 1 1 vars not converged, max err/tol -0.52510e+01 block: cstr model: rcstr ** error m-bal loop did not converge in 50 iterations. check stoichiometry/molecular weights. loop $olver01 method: secant iteration 2 1 vars not converged, max err/tol -0.51274e+01 block: cstr model: rcstr ** error m-bal loop did not converge in 50 iterations. check stoichiometry/molecular weights. loop $olver01 method: secant iteration 3 * warning either solution outside bounds or spec function is not monotonic. 1 vars not converged, max err/tol -0.40153e+01- simulation calculations completed ...查看更多
