@NoWayTime 在 空气热物性参数为列表形式时报错：Energy -> temperature conversion failed to converge 中说：
您好，我在依据nist数据库中的物性参数修改物质的Cp和H后，也出现了这个问题，请问您是怎么解决的。
我的问题出在边界条件设置不合理，建议您可视化界面看一下出现异常的位置，再分析具体原因，有问题我们再沟通！

@gzs20 您好，我也在尝试将热物性改为表的形式，但是我仅仅将rho修改成为列表查询，并没有将其他的热物性修改为列表查询。但是结果显示，我的类里面的H.(scalar p, scalar T)出现问题
我当初是边界条件不合理导致的，出现了一些异常高温点和高流速点，修改完就正常了，建议您parafoam看一下结果，观察问题出现在那个位置处；具体分析，是网格的问题还是边界条件的问题；
