Hi OF users,

I implement a new LES model and successfully compiled with OF 3.0.1 (the files and options are attached below). The new LES model is wrapped into the library libuserincompressibleLESModels.so in the folder $(FOAM_USER_LIBBIN).

To test this model, I included in the controlDict a line like

libs("libuserincompressibleLESModels.so");

However, the pimpleFoam does not recognize this new model, telling me the unknown LESModel error.
(If I use the same configuration and use the build-in LES model, the case runs succusfully.)

Any ideas on the problem?

Thanks

Make/files:

newLESModel/newLESModel.C
LIB = $(FOAM_USER_LIBBIN)/libuserincompressibleLESModels

Make/options:

EXE_INC = \
-I$(LIB_SRC)/TurbulenceModels/turbulenceModels/lnInclude \
-I$(LIB_SRC)/finiteVolume/lnInclude \
-I$(LIB_SRC)/meshTools/lnInclude

LIB_LIBS = \
-lfiniteVolume \
-lmeshTools

I basically narrow down the problem to the addtoruntimeselection.
Since the version 3.0.x has a different structure for addtoruntimeselection which separates the implementation of basic LES models (e.g., smagorinsky) and addtoruntimeselection, the solver simply does not know the user-defined new model.

In v2.0.x, it is pretty straightforward, just adding these two lines to the implementation

defineTypeNameAndDebug(NEWMODEL,0)
addToRunTimeSelectionTable(LESModel, NEWMODEL, dictionary)

This does not work anymore in v3.0.x.
Any ideas to add the new model to the runtime selection table in v3.0.x?

Many thanks.

Foam gurus,

How to add the user defined turbulence model to the runtime selection table in OF 3.0.x?

Any ideas or threads?

Many thanks.

Solution:

creat a file named makeMyTurbulenceModels.C and compile the new model (newmodel.H) by compiling this file.

makeMyTurbulenceModels.C

#include "IncompressibleTurbulenceModel.H"
#include "incompressible/transportModel/transportModel.H"
#include "addToRunTimeSelectionTable.H"
#include "makeTurbulenceModel.H"

#include "LESModel.H"

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

namespace Foam
{
  typedef IncompressibleTurbulenceModel<transportModel> transportModelIncompressibleTurbulenceModel;
  typedef LESModel<transportModelIncompressibleTurbulenceModel> LEStransportModelIncompressibleTurbulenceModel;
}


#include "newmodel.H"
makeTemplatedTurbulenceModel(transportModelIncompressibleTurbulenceModel,LES,newmodel);

Make/files

makeMyTurbulenceModels.C

LIB = $(FOAM_USER_LIBBIN)/libuserincompressibleLESModels

Make/options

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

LIB_LIBS = \
    -lincompressibleTurbulenceModels

Hope it is helpful.
