Default BSL-EARSM implementation in OF-7

Katta is on a distinguished road

My aim is the implementation of the compressible BSL-EARSM model in OF-7. In the following, I have described the steps which were already taken.

What was already done:

  • make the newest version of BSL-EARSM (written for OF-4.1) working as compressible model in OF-4.1 - see attached file bslearsmComp_OF4.1
  • comparison of kOmegaSSTBase.C of OF-4.1 and OF-7 to detect syntax differences between the OF-versions and adaption of bslearsmComp.C (which is most similar to kOmegaSSTBase) → no more errors concerning variables and equations occurring - see attached file bslearsmComp_OF7
  • adaption of Make/files and Make/options towards the changed file-structure of OF-7
  • usage of the makeTurModel.C- file from this blog and comparison of the syntax of the files used as basis for makeTurModel.C from OF-4.1 and OF-7:
    • OF/src/TurbulenceModels/compressible/turbulentFluidThermoModels/makeTurbulenceModel.H:
      • same syntax for OF-4.1 and OF-7
      • definition in OF-4.1 includes #include „EddyDiffusivity.H"
      • definition in OF-7 added in lines 26-35: #define makeTurbulenceModelTypes(…)
    • OF/src/TurbulenceModels/compressible/turbulentFluidThermoModels/ turbulentFluidThermoModel.H:
      • same syntax for OF-4.1 and OF-7
      • OF-7 added line 49 and line 63 including the laminar mode
      • in OF-7 is a file „…/turbulentFluidThermoModels.H“ existing which is not there in OF-4.1
    • makeTurModel.C -file in OF/user-7/…run/bslearsmComp- file:
      • change of name of include-file: „laminar.H“ in OF-4.1 changed to
        „laminarModel.H“ in OF-7
        → error: log.wmake-file in the bslearsmComp-file of OF-7

My estimation is that the problem for not correctly compiling the bslearsm model is caused by the changed syntax from OF-4.1 to OF-7. Maybe, therefore the macro "createBaseTurbulenceModel" in makeTurModel.C can't work correctly as in OF-4.1?

Any help is appreciated.

mAlletto will become famous soon enough
can you post the compiler errors?

The problem of not correctly compiling the library of the compressible bslearsm model for OF7 is solved - many thanks to Hassan Kassem.

The working code is attached.

To compile the library on your OF7-system just copy the attached file in the run-directory and execute:
wmake libso
wmake libso

To use the turbulence model:
  • add to the system/controlDict-file:
  • add to the constant/turbulenceProperties-file:
    simulationType RAS;

    RASModel bslearsmComp;

Attention: there may occur errors if you try to use an incompressible solving solver with the compressible bslearsm model.

Best regards,
