Calculating YPLUS and Compiling Multiple C files

sanjibdsharma · August 10, 2009, 07:07

Hi,

I am new to OpenFoam and trying to determine YPlus values from Turbulent flow. I found the yPlusRAS.C file. However, I do not know how to compile this along with any other flow solver, for eg. simpleFoam.C. I have tried to change the Make file in the solver as:

simpleFoam.C
yPlusRAS.C

EXE = $(USER_APP_BIN)/ simpleFoam

But this did not work.

Can anyone suggest a way to determine YPlus and also how to compile multiple C files in OpenFoam.

Thanks a lot in advance.

Sanjib

This doesn't really make sense. Do you want to calculate yPlus values for post processing, or do you need them during the calculation?

Look inside yPlusRAS.C. If you want to calculate a field of yPlus values, you'll see on line 54 that the field is declared and initialised. On line 99, the yPlus values are calculated. You'll see that they come from RASModel.
