方 法一:采用自带的foamMonitor来输出残差我们首先需要将OpenFOAM中输出残差的文件拷贝到算例的system目录下,我们可以采用以下命 令在OpenFOAM的安装目录下查找该文件 find /opt/openfoam4/ -name residuals 然后我们使用cp命令将查找到的residuals文件拷贝到算例system文件夹下 cp “/opt/openfoam4/etc/caseDicts/pos...
gnuplot Residuals - in the main-case-folder.Step 4:Another good indicator for the calculations convergence is the forces-plot. Therefore you have to set the function in the controlDict that calculates the forces and forceCoeffs. See threadhttp://www.cfd-online.com/Forums/ope...es-of15-3.ht...
方法2:利用进行残差显示 对于,可以利用以下命令添加residuals字典: 打开文件,添加语句: 然后运行案例: 图形显示结果如下图所示。 若要使用进行残差显示,需要首先安装pyFoam,这可以使用pip或pip3进行安装。 安装完毕后,可以使用或进行残差查看。 输出图形如下图所示。 注: 不建议使用pyFoam,虽然很多时候比较方便,但pyFoa...
然而,在输出的log文件中睁大眼睛去找Courrant number和residuals是一件很痛苦的事情。这时候看见旁边电脑上的star CCM+输出的花花绿绿的残差图,是不是感觉OpenFOAM可以从入门到放弃了? 其实大佬早就内置了脚本用来读取log文件的全部信息。运行完case之后,在终端输入 ...

All the solutions were considered fully converged when sum of scaled residuals was below 10− 4. Before stopping the calculations, relative variations of key physical variables, such as flow velocities and temperature, were imposed to be lower than 10− 4 m/s and 0.1 K, respectively. All ...
