问题描述
我在使用 ThermoSysPro 库的初始化过程中遇到错误.
I met an error during initialization when using ThermoSysPro library.
看起来Turbine5.Pe 比Turbine2.Pe 大，所以结果是否定的.不过我查了一下参数，应该不会有这样的问题.
It seems like the Turbine5.Pe is larger than Turbine2.Pe, so the result is negative. but I checked my parameters, there shouldn't be such a problem.
这是因为非线性求解器无法求解下图中的方程吗?
Is this because the nonlinear solver couldn't solve the equation in the following picture?
推荐答案
没有足够的信息，我建议在仿真设置中设置细节和/或非线性迭代>调试>非线性求解器诊断以获得更多信息.
There is not enough information and I would recommend to set Details and/or Nonlinear iterations in Simulation setup>Debug>Nonlinear solver diagnostics to get more information.
导致问题的完整表达式是sqrt((Turbine2.Pe^2-Turbine5.Pe^2)/(Turbine2.Cst*Turbine2.proe.T))
The full expression causing the problem is sqrt((Turbine2.Pe^2-Turbine5.Pe^2)/(Turbine2.Cst*Turbine2.proe.T))
由于两个 Pe 值都固定为 true，因此它们似乎不太可能是错误的，但如果没有完整的模型，则无法看到.
Since the two Pe-values have fixed=true it seems unlikely that they are wrong, but it is impossible to see without the complete model.
但是，也有可能 Cst 或 proe.T 为负数，或者基于其他值计算为负值.
However, it is also possible that either Cst or proe.T is negative, or computed to a negative value based on other values.
没有完整的模型是不可能的.
Without a complete model that is impossible to tell.
