split 进出物料 不平衡一些错误
附件请查看1. DS-ALKLT 设计规定是改变冷却水流量来实现对温度的控制 ， 怎么出现这种错误
* WARNING WHILE CHECKING INPUT SPECIFICATIONS FOR VARIED VARIABLE IN
DESIGN-SPEC: "DS-ALKLT"
YOU ARE VARYING A VARIABLE OF AN INTERMEDIATE STREAM
STREAM RESULTS MAY BE INCONSISTENT WITH THE BLOCK UPSTREAM
2. split 和闪蒸模块 进出物料不平衡
所以在不知道实际分离器各股流量时， 不知道哪里错了，怎么设定。

是否设计规定由问题，导致物料不能平衡 iamchyna 发表于 2018-7-12 09:41 static/image/common/back.gif

已添加附件，正文没有添加成功，请问这是设计规定有问题么？还是split设定有问题。
我感觉：
因为刚开始split后的各物流分率并不知道，所以只能设个初值，然后实际模拟出来的分率应该取决于物流进入换热器需要发到设计规定的值。
是否正确？

已经上传了在三楼 已经收敛，还是需要单个模块单独模拟，设计规定的变量范围设定也需要尽量接近最终值，以便程序便于收敛。
