[immortality]

I have used :

simulationType  laminar;//RASModel;//

but rhoSimpleFoam solver complains about k! why?

Hi Ehsan,

Don't you know that turbulence settings are usually defined in OpenFOAM on two files?
Namely "constant/RASProperties" (or "constant/LESProperties") and "constant/turbulenceProperties"?

Best regards,
Bruno

Since Ehsan sent me the case, the problems are:

• The file "constant/RASProperties" did not use this setting:
  

  RASModel        laminar;

  I know, it might seem weird, but the problem is that some solvers directly access the file "constant/RASProperties" and ignore "constant/turbulenceProperties", while others need this latter file.
• After that, the problem was:
  

  --> FOAM FATAL IO ERROR: 
  keyword laplacian(alphaEff,h) is undefined in dictionary "/home/user/Desktop/Misc/HeatExchanger/system/fvSchemes.laplacianSchemes"

  Which is just a matter of editing the file "system/fvSchemes" and adding the entry "laplacian(alphaEff,h)" to "laplacianSchemes".
