这是我在使用 OpenModelica 软件时收到的最常见错误之一。
我已经了解当系统参数发生冲突并且彼此不一致时，通常如何触发此错误。
我已经尝试省略我认为对我的系统不是必需的系统参数，但是似乎没有任何东西可以解决该错误。
我的系统一开始就非常简单。目前，我正在进行子组件验证过程，以正确构建有效的 Rankine Power 模型。该子组件侧重于 (2) 个热交换器中的 (1) 个，该热交换器将用于双 HX 系统，该系统在高压和低压涡轮机之间包含再热过程。
该子组件试图描述来自泵的冷凝液体状态的水，在该状态下它将通过热交换器“过热器”，在那里它将状态从压缩液体变为过热蒸汽。然后，这种蒸汽将被送入高压涡轮机并返回压力槽。
我已经完成了对我的系统的手动计算热力学分析，并且知道出口温度和焓。但是，这些出口参数是我选择删除的一些参数，因为我觉得我会让系统解决它们，而不是告诉它应该计算什么。删除这些值以解决错误也不起作用。
如果您有任何想法、建议或考虑，请告诉我！下面我将代码发布到我一直在做的事情上。再次感谢！
