新手求问冲击波管喷出的低马赫数supersonic的 边界条件问题

@李东岳
谢谢李老师。还是跟之前一样的错误。。tube里面的气体不往前面流动。
这个是把网格换成六面体的case

感谢李老师回复!
用snappyHexMesh画六面体网格后发现问题解决了!!
但是还有个问题为什么画的网格感觉好多小的瑕疵。。。。而且这还是完全没有细化也没有添加layers的情况。。
还想请老师帮忙看下snappyHexMeshDic。
这个是snappyHexMeshDic:
https://www.dropbox.com/s/ehr4vknk6injnvr/snappyHexMeshDict?dl=0这个是case

@李东岳 在 新手求问冲击波管喷出的低马赫数supersonic的 边界条件问题 中说:
volScalar
感谢回复
这个代码的意思是修改求解器重新建立一个可单独计算密度的场吗,如果是的话 还需不需要在ControlDic里加rho function。
然后代码是不是要放在 applications/solvers/compressible/sonicFoam/createFields.H里面?不知道是不是我用的Mac系统,找了一下午找不到createFields.H这个文件。。applications文件夹也没有找到。这些文件是不是隐藏在docker里面,怎么打开这些隐藏文件?
麻烦老师了🙏Ryo

@李东岳
李老师,现在发现openfoam Mac版的applications文件夹好像只存在于docker模拟的虚拟机里面在Mac上找不到。用vim在docker状态下找到createfields.H文件了,用vim打开后发现里面已经有一个rho的场存在,代码和您写的是一样的。
是不是要像速度场那样 加上IOobject::MUST_READ,IObject::AUTO_WRITE这些代码才行,现在还没有完全理解这些代码的含义。比如 "Reading field U\n" << endl里面的这个n和endl是什么意思。。网上找了很久也没有发现答案。希望老师能解答一下🙏 -
@李东岳
感谢回复🙏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🙏 -
@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。
🙏 -
@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🙏
