Please take your own time, reply me just when you are leisure ,I will try my best to solve the problem on myself .

really thanks a lot for so long. best wishes !

:oooooooooooooo

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。

你按照我这样分block
有点事我要出去

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

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

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。。

🙏🙏

你点击一下这个试试

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。。

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

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

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🙏

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

//EXE_LIBS = \下面加
-lmeshTools \

试试

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。
🙏

现在所在的这个研究室在做用独创的激光CT法观测从冲击波管里面喷出的冲击波密度场。 所以我现在想用OpenFOAM作为CFD工具模拟出冲击波的密度场，然后再和真实实验中的图像数据做对比。
sonicfoam里面计算出的结果没发显示密度，在网上找了个代表密度函数的代码放到controldict里面后可以显示密度了但是不能直接在0文件夹里面调节初始密度场。
这是放在controlDict里面的代码

现在把Oobject::MUST_READ,IObject::AUTO_WRITE加到createFields.H里面后，计算时仍然不读取0文件夹里面的密度边界条件和初始密度场。。

想问还需要编译什么才能直接调节初始场的密度。
麻烦老师啦🙏
