我正在尝试建模和复制OpenModelica库中的“ Open Brayton Power Cycle”，并且遇到了一条毫无意义的错误消息。该错误消息是sourceMassflow.mo和CombustionChamber.mo之间不兼容的结果，所有这些都来自modelica库，并且以与库Brayton示例相同的方式进行连接。
从modelica库完全复制“ Brayton电源循环-打开”之后，发生了此错误。
这是我收到的错误。这则消息几乎证明了这两个组件是相互兼容的，但是我无法弄清它们为什么不能“一起工作”。
[11] 14:18:40 Translation Error
[BraytonCycle_First: 49:3-50:84]: Incompatible components in connect statement: connect(sourceMassFlow1.flange, combustionChamber1.inf)
- sourceMassFlow1.flange has components {C_outflow, Xi_outflow, h_outflow, m_flow, p}
- combustionChamber1.inf has components {C_outflow, Xi_outflow, h_outflow, m_flow, p}
我将库的所有组件参数复制到了我的模型中，并期望这可以解决问题。我没有做任何事情可以解决此问题，由于上述错误消息，这些模型似乎可以兼容。
任何帮助或建议将不胜感激。
答案 0 :(得分：3)
该模型可以编译，但是在仿真方面存在问题。也许您可以解决这些问题。我更改了所有重新声明，以使用ThermoPower.Media。*介质。
