Implementing v2f turbulence model in 2.1.x - GName not declared error
 
hi,

Im trying to implement the v2f model in version 2.1.x but without any success.

steps followed:

1) Downloaded the v2f.C and v2f.H files from https://github.com/OpenFOAM/OpenFOAM-2.2.x

2) created a new folder in my /src/turbulenceModels/incompressible/RAS/v2f

3) created a Make folder with files & options:

Files:
Code:

v2f.C
LIB = $(FOAM_USER_LIBBIN)/libmyincompressibleRASModels

options:
Code:

EXE_INC = \
    -I$(LIB_SRC)/turbulenceModels \
    -I$(LIB_SRC)/finiteVolume/lnInclude \
    -I$(LIB_SRC)/meshTools/lnInclude \
    -I$(LIB_SRC)/transportModels \
    -I$(LIB_SRC)/turbulenceModels/incompressible/RAS/lnInclude
LIB_LIBS =

4) used the command 'wmake libso'

but resulted in the following error:

Code:

wmakeLnInclude: linking include files to ./lnInclude

v2f.C:367:34: error: ‘GName’ was not declared in this scope
make: *** [Make/linux64GccDPOpt/v2f.o] Error 1

‘GName’ was not declared in this scope is the error. Any ideas where im going wrong?


Thanks.

From 2.2.2's $FOAM_SRC/turbulenceModels/incompressible/turbulenceModel/turbulenceModel.H:

Code:

inline word GName() const
{
    return word(type() + ":G");
}

also IIRC in 2.1.x it should be type() + ".G"

Hi Alexey,

Thanks for the suggestion. Do you suggest to include the code you have mentioned in my 2.1.x ~/turbulenceModel.H as it is in 2.2.x ? (because you have replaced :G to .G) ? Any idea why this function is included in the 2.2.x and not the 2.1.x?

Hi,

You've got several options, two of them are:

1. Replace call to GName() with "RASModel::G" (I've just checked the naming in 2.1.0's kEpsilon.C).

2. Add GName method into turbulenceModel class (turbulenceModel.H) like
Code:

inline word GName() const
{
  return word("RASModel::G");
}

I think string "RASModel::G" was changed to call to GName() for the ease of future renaming of G field.
