I wish to run a simulation over a 2D cylinder to see the effects of different discretization schemes on the results. I have attached my fvscheme code in the picture below. Running this using simpleFoam gives me following error:
--> FOAM FATAL IO ERROR: attempt to read beyond EOF file: D:/Random_stuff/OpenFoam/cylinder/system/fvSchemes.divSchemes.div((nuEff*dev2(T(grad(U))))) at line 36. From function virtual Foam::Istream& Foam::ITstream::read(Foam::token&) in file db/IOstreams/Tstreams/ITstream.C at line 82. FOAM exiting The turbulence is 'off' and it is a steady state simulation. Can anyone please tell me as to why I am getting this error? |

Hello,
There is a specific forum for OF, you may have better luck posting this on there: https://www.cfd-online.com/Forums/openfoam-solving/ |

Your fvSchemes file is improperly formatted. It usually means you are missing a space or a ; somewhere.

But it worked with this code. I wonder why it doesnt work with schemes that I had used earlier.
gradSchemes { default Gauss linear; } divSchemes { default none; div(phi,U) bounded Gauss linearUpwind grad(U); div(phi,k) bounded Gauss limitedLinear 1; div(phi,epsilon) bounded Gauss limitedLinear 1; div(phi,omega) bounded Gauss limitedLinear 1; div(phi,v2) bounded Gauss limitedLinear 1; div((nuEff*dev2(T(grad(U))))) Gauss linear; div(nonlinearStress) Gauss linear; } laplacianSchemes { default Gauss linear corrected; } interpolationSchemes { default linear; } snGradSchemes { default corrected; } |
