新手求问冲击波管喷出的低马赫数supersonic的 边界条件问题

[Ryo]

@李东岳 李老师，现在想重新编译时按照http://openfoamwiki.net/index.php/How_to_add_temperature_to_icoFoam。 这个教程想练一遍，发现wmake的时候出现错误

我在想是不是用mac的原因于是 我又在虚拟机上（linux mint）上试了下，直接告诉我wmke command can not found
。。不知道时怎搞的了。。能帮忙看下哪里出错了吗。
🙏

[Ryo]

@ryo 不是wmke是 wmake，刚才手误

[李东岳]

在你的Make/option里面添加

//EXE_INC = \下面加
-I$(LIB_SRC)/meshTools/lnInclude \

//EXE_LIBS = \下面加
-lmeshTools \

试试

[Ryo]

@李东岳 谢谢 回复。🙏
Make/option里面本来就有这些码。

[李东岳]

不好意思没有mac不能提供建设性意见 :big_mouth:

[Ryo]

@李东岳 感谢老师回复 🙏

Mac上还是没有找到什么原因wmake出错，但是在虚拟机（Linux Mint）上在按照openfoam wiki上添加温度的教程编译成功了。
发现 在createfields.H里加Oobject::MUST_READ,IObject::AUTO_WRITE，和在/systym/controlDict里面加

效果一样 都只是根据初始p，U，粘度等来计算密度，不能直接读取0文件夹里面的rho文件。。。
这是0文件夹里面的rho文件 虽然设置的是1但是计算后在paraview上显示是0.23

怎么才能跟fluent一样直接调节初始场密度呢。
麻烦老师在看下🙏

[Ryo]

@李东岳
老师好！发现openfoam是不能直接进入密度场的因为openfoam用的是kinematic viscasity.fluent用的是动力粘度。

所以感觉还是得调节p，之前的压力边界条件我设置的是outlet为0.2大气压，inlet为zerogradient。现在调换后inlet为0.2大气压，outlet为zerogradient，initial为1个大气压。然后按照

更改fvscheme后达到预期的冲击波外的区域密度场都1左右，但是发现冲击波前面的涡很微弱。
这是实验得到的图像。冲击波前面有很明显的蓝色的涡。

这是openfoam得到的图像，冲击波前面基本没有涡

[李东岳]

volScalarField rho
    (
        IOobject
        (
            "rho",
            runTime.timeName(),
            mesh
        ),
        thermo.rho()
    );

OpenFOAM里面的密度是通过thermo.rho()更新的，因此你不能直接给密度。

更改fvscheme后达到预期的冲击波外的区域密度场都1左右，但是发现冲击波前面的涡很微弱。这是实验得到的图像。冲击波前面有很明显的蓝色的涡。

云图看起来不是很客观，最好出plot图看看

[Ryo]

@东岳 Hi!
又要来麻烦老师了🙏

之前的涡的存在问题已经解决。原因是因为压力边界条件设置问题，还有发现k和epsilon之前按照公式算的是10的5次方级别的数字 但是我把他调节成0.5也能算而且精度更准，这个还不知道什么原因。。

现在（其实从之前）就有个关于paraview的问题，把data放到paraview里面显示rho跑第一遍的colour legend和先显示p跑一遍在切换到rho显示的colour legend有些许的不同。

这是显示rho跑第一遍的图 colour legend只显示到0.23

这是先跑完一遍p在切换到rho， colour legend就可以显示到0.06

求老师给点指示

[李东岳]

什么是“先跑一遍rho和先跑完一遍p”...

[Ryo]

@东岳
sorry 😂
先跑一遍rho：把data放到paraview里面选择rho然后点击play

先跑一遍p在调节到rho：把data放到paraview里面先选择p然后点击play在从p调节到rho

想说的意思可能就是第一遍play显示的数据图像和play完第一遍后切换到其他性质（比如从密度切换到压强，压强切换到密度）后在切换回来显示的不一样。一样的data为什么会显示的不一样呢？ 问题解释的可能有点傻，请见谅。。

[李东岳]

你点击一下这个试试

[Ryo]

@东岳
懂了，多谢老师。

[Ryo]

@东岳
又来麻烦老师了。之前用snappyHexMesh做的网格感觉不好现在想换用icem cfd来做，弄了好几天发现喷口旁边座位阻碍物的圆柱的网格有大瑕疵（表面的都很好），找了很多视频里面都没有找到该怎么去掉圆柱里面这些不需要的网格。
另外icem cfd做好的网格怎么导入openfoam和paraview现在也没找出来方法。 请老师给点指示。

🙏🙏

[Regina]

@ryo 不太明白为什么动力粘度就不需要单独设置密度了呢，那如果我需要设置成水的属性，密度为1000kg/m^3，运动粘性系数=1.139×10^-6Pa*s。除了修改属性设置文件transportProperties中的粘度，我怎么保证密度也是我想要的1000kg/m^3呢？希望能指导一二，跪谢

[Ryo]

@regina Hi!

openfoam不能直接进入密度场，密度是由其他物理条件（p，u,t...etc）计算出来的，我也想直接设置密度😭。。 我是通过调节初始p,u,t来调节初始的密度。sorry，不知道帮到你了没有。。

另外你知道我这网格为啥会有这问题吗？ 然后我把这网格用fluentToFoam了下发现报错

之前用gmesh这样gmshToFoam都没问题可以转。。

[李东岳]

@Ryo

你的网格质量很差，导入的时候有可能出现问题。把你的tin文件上传一下我给你画一个

这个帖子竟然48楼了

[Ryo]

@东岳 多谢老师
这是tin文件 传到dropbox上的
https://www.dropbox.com/s/4zw6pr4f9hvy86v/12345.tin?dl=0
这是prj文件在dropbox上的
https://www.dropbox.com/s/997ohw1j55uw2z3/12345.prj?dl=0

我用snappyHexMesh弄的网格数在180万左右，网格少点没事，感谢老师啦Thanks♪(･ω･)ﾉ

[李东岳]

你按照我这样分block
有点事我要出去

[Ryo]

@东岳
多谢老师回复 现在没搞懂这些边是怎么添加上去的 （上面的斜线和右边圆里面的不规则四面体）sorry 刚上手这个软件 。
然后我简化的画了网格 还有之前的问题。。

这是我画的切的block

这是画的网格
sorry 实在是有点太小白了 麻烦老师了。
