Hello,



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
  • source of the BSL-EARSM-Code: https://bitbucket.org/khedar/of-dev/...r/bslearsm4.1/
• 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 http://hassankassem.me/posts/newturbulencemodel/ 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.

Best regards,

Katharina

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:
  libs(
  "libbslearsmComp.so"
  );
• add to the constant/turbulenceProperties-file:
  simulationType RAS;
  
  RAS
  {
  RASModel bslearsmComp;
  ...
  }

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




Best regards,
Katharina
