@李东岳 在 函数调用出现未知类型 中说：

const Thermo& thermo是什么变量？

是个Thermo变量。Thermo是一个类型。

谢谢李老师！该如何定义Thermo类型的变量呢？我想调用Tvenewdefinition这个函数，需要输入该类型的变量，但我输出thermo发现是个关于组分信息的矩阵，不知道该如何定义。

有一个比较基础的问题想要请教：仿照其他函数格式构造下列函数，目的是调用Tv温度场，必须加入const Thermo& thermo才能实现thermo.Tv() 调用，但不了解const Thermo& thermo是什么变量？Tvenewdefinition该如何调用？
scalar Tvenewdefinition
(
const Thermo& thermo
) const
{
return thermo.Tv();
}

当前化学反应速率均只包含一个控制温度，想更改成与两个温度相关，通过插值读表获取反应速率。编写新函数inline scalar HoffertLienReactionRate::interpolate(double T) 实现上述功能，代码可以成功编译，但输出Tv检查时发现其值一直为0，这是不是表示未能成功调用？具体代码如下。向各位大佬求助！！！HoffertLienReactionRate.H HoffertLienReactionRateI.H

求助，目前在使用hy2Foam求解器计算类似乘波体外形，已经计算过钝头算例可以得到收敛解。但目前计算外形相对复杂，二维计算，计算域为1*0.55m，网格数量42000。计算过程中经常报错，求问有没有什么调试建议。下面是报错信息。

@biaowai 在 使用mapFields 操作更改网格计算出错 中说：

印象可以修改差值方式或者用mapFieldsPar试试

我用的1706版本，尝试过修改差值方式还是不行。去试试mapFieldsPar。

@学流体的小明 确实是数据插值有问题，手动把右下角网格点数据改掉了，大概两行，一百多个点，现在可以跑起来了

计算域不变，边界条件不变，将12000个网格加密到15000个后，使用 mapFields -consistent ../sourceFolder 命令进行结果映射的时候，映射之后的场是这个样子，感觉分布不合理，是不是 mapFields 操作有问题。

使用hy2Foam求解器做RamC模型验证，在驻点线画图时发现异常，组分质量分数结果使用线性坐标为正常曲线，如下所示。
但当转换为指数坐标时，曲线出现奇怪波动，请问是为什么呢？

但计算过程中会出现CFL数突然增大之后报错的问题Mean and max Courant Numbers = 0.0196702 0.2

已经解决了，需要在controlDic中修改输出精度，至少在12以上

使用pointwise输出二维网格，网格检查结果良好
但是用
makeAxialMesh -case ~/OpenFOAM/sy-v1706/run/00mesh -axis symmetry -wedge BaseAndTop
collapseEdges指令生成楔形网格后检查网格质量，正交性变差，导致计算不断报错。

想请教一下，相同算例直接计算可以得到收敛结果，但并行运算时算到大概一半时间时报错。下面是decomposeParDict文件和报错信息。
报错信息.txt

@ShaneHEEE 设置的是从x方向流入 我再检查一下

@李东岳 好的，谢谢老师，我再检查看看

已经计算至0.001s，按照我设置的初始速度应该已经走过一半距离，但现在数值还是只存在与第一层网格。有点搞不懂到底是哪个部分出现了问题

不是标准算例 是自己建的模型 是可压缩流动

使用hy2Foam求解器计算三维翼型流场过程中出现内场维持初值不变的情况，建立一个简单的长方体算例出现相同情况，仅入口两层网格存在数值，下面是计算至0.001s的情况 采用100x10x10的结构化网格，下面是入口，上面是出口，四周设置为零梯度条件。

仿照https://www.cfd-online.com/Forums/openfoam-solving/60471-call-fortran-program-openfoam.html进行Fortran程序的调用，编译过程中报错： from chemistryModel/rho2ChemistryModel/rho2ChemistryModels.C:37:

phypro(&TG, &TE, &PT, &PE, &CON[0], &CP_FINAL[0][0], &H_FINAL[0][0], &MIU_FINAL, &K_FINAL[0]);
但仿照https://www.cnblogs.com/snake553/p/6962386.html编写C++程序可以实现Fortran程序的调用

增加了一种读取表格计算物性的方法，编译无报错但实际应用时显示下列报错信息

@Elysiumor 在 使用hy2Foam求解器，更换bluntedCone算例网格便计算报错 中说：

@sy2315317 请问您按照官网操作，使用gnuplot可以实时查看残差吗

不能，提示缺了一个库，但装不上
