U+-Y+

这个gnuplot脚本是我用于处理Incompact3d产生出来的统计结果(如何统计部分，暂时未写)的画图脚本。

数据段

注意gnuplot处理数据文件按照空行划分index部分。所以下面的部分总共有四个index，调用方式是

• plot “文件名” index 0 第一部分文件信息的打印
• plot “文件名” index 1
• plot “文件名” index 2
• plot “文件名” index 3

具体看gnuplot脚本部分。

处理结果

一些实时监测部分

执行部分：

a.sh

mpirun -np 8  incompact3d  >> tail.out &

获取信息部分

image.sh

more tail.out | grep DIV | grep U* |grep Max|sed '/final/d'| awk -F'=' '{print $2}' |sed '1,3d'> divu
more tail.out | grep UT | awk  '{print $4}'|sed '1,2d' > flow-rate-correction-factor

#more tail.out | grep zhao | awk '{print $2,$3,$4}' > stretching

more tail.out | grep PHI | grep max|awk -F'=' '{print $2}' > PHImax

more tail.out | grep PHI|grep MOYEN | awk  -F":" '{print $2*10^4}'> PHImoyen
#gnuplot monitorFLOWRATE.gnu

bash monitor.sh

打印部分

整合部分

cut -c的目的是获取具体对应的时间步,然后把所有的png相关信息 放到对应时间步文件夹中。

cd /home/Cedric/diric/src && more tail.out |grep Time|awk '{print $4}' |tail -1|cut -c 1-6 |awk '{cmd="mkdir step"$1;system(cmd);system("sh image.sh");cmd2="mv *.png step"$1;system(cmd2);} '

# END{cmd3="mv dudy* umean stress step"$1;system(cmd3)}

实时浏览

切换到对应的文件夹
$ python -m SimpleHTTPServer 

然后就可以打开 127.0.0.1:8000进行浏览了。

You can also use crontab to execute program in real time

crontab -e

Then you can copy the info below,but modified the datatime.
