计算完成并使用 reconstructPar 重组计算结果之后，使用 postProcess -func yPlus 查看Y+，报错显示：
--> FOAM FATAL ERROR:
Unable to find turbulence model in the database
From function virtual bool Foam::functionObjects::yPlus::execute()
in file yPlus/yPlus.C at line 185.
FOAM exiting
使用下面的命令之后，不再报上面的错误：
simpleFoam -postProcess -func 'yPlus'
能够正确计算Y+:
