Calculation of yPlus

sasanghomi · January 28, 2013, 11:27

Hi every body,

I have a compressible case that the solver is sonicTurbDymEngineFoam ,
actually it simulates the cold flow in an internal combustion engine.
The turbulence model is standard k-epsilon with wall functions
and I want to calculate yplus by using yPlusRAS utility but I have an error :

--> FOAM FATAL IO ERROR:
keyword nu is undefined in dictionary "/home/sasan/Desktop/ProfJasak/constant/transportProperties"

file: /home/sasan/Desktop/ProfJasak/constant/transportProperties from line 17 to line 19.

From function dictionary::lookupEntry(const word&, bool, bool) const
in file db/dictionary/dictionary.C at line 396.

This case is compressible and does not have transportProperties dictionary.
Can any one help me??

thanks,
Sasan.

every body I got it...

you must use:

Code:

yPlusRAS -compressible
