aspen 回归模型参数无法收敛怎么办？ 我也出现以上错误，错误说明如下： *** drs converged in 21 iterations, but constraints are not tightly converged *** * warning while executing drs case: "r-1" constraints not (tightly) satisfied for this case. ** error while executing drs case: "r-1" drs results do not agree with three-phase flash results. - rerun with a different set of parameter initial values - recheck the data in the data-group paragraphs - check std-dev for specifications that are too large ! data regression completed with errors 请高手指点。 奇怪的是，我用aspen plus算的时候出现以上错误，改用aspen properties回归计算成功，纳闷！查看更多
