ASPEN 热力学一致性检验? 大家好: 最近在看aspen热力学一致性检验的案例,自己也在尝试,对有些二元物质热力学一致性检验能够通过,也有些显示不能通过,但是还有一些显示not performed,已经确认以下条件: 1 数据点大于5 2 数据点中没有纯物质,且已包含整个浓度范围 3 数据是直接选用aspen内部气液相平衡数据 但是在运行时出现了以下两种情况,不知道是回归出问题还是其他,现将问题描述如下: 第一种: *** drs converged in 2 iterations, but constraints are not tightly converged *** * warning while executing drs case: "dr-2" constraints not (tightly) satisfied for this case. 第二种: begin case dr-1 time = 0.00 starting point time: 0.00 *** measurement adjustment failed - britt-luecke is likely to fail *** bl-iter: 1 ssq: 0.638898e+08 rel change: 0.00 time: 0.02 bl-iter: 2 ssq: 0.134691e+08 rel change: 0.382e-06 time: 0.02 final ssq: 0.397102e+07 *** drs stopped due to 10 line searches failed *** * warning while executing drs case: "dr-1" line search failure for this case. 还望各位大神能够解答 多谢 查看更多
