Howdy Folks:
I am wondering if others experience a similar issue: I have a case using rhoPimpleFoam that works on (single and multiple) processes on a single machine. But the same job would choke on the following error: Code:
--> FOAM FATAL IO ERROR: keyword div((nuEff*dev2(T(grad(U))))) is undefined in dictionary "IOstream.divSchemes" file: IOstream.divSchemes from line 0[10] Code:
divSchemes { default none; div(phi,U) Gauss limitedLinearV 1; div(phi,h) Gauss limitedLinear 1; div(phi,K) Gauss limitedLinear 1; div(phid,p) Gauss limitedLinear 1; div(phi,epsilon) Gauss limitedLinear 1; div(((rho*nuEff)*dev2(T(grad(U))))) Gauss linear; } Thanks in advance, Gerry. |

Maybe the excessive bracketing?

I think you are using a different solver. Not what you need.
rhoPimpleFoam need div(((rho*nuEff)*dev2(T(grad(U))))) what you got in fvSchemes. But the solver what you are running need div((nuEff*dev2(T(grad(U))))). I think this is an incompressible solver. Can you check the beginning of the log? |

Folks:
I think I know what happened. I have a divergence definition for rho*nuEff, but I also need one for rho, so that OpenFOAM knows what to do with rho *and* nuEff. So my divSchemes looks like Code:
divSchemes { default none; div(phi,U) Gauss limitedLinearV 1; div(phi,h) Gauss limitedLinear 1; div(phi,K) Gauss limitedLinear 1; div(phi,rho) Gauss linear; div(phid,p) Gauss limitedLinear 1; div(phi,epsilon) Gauss limitedLinear 1; div(((rho*nuEff)*dev2(T(grad(U))))) Gauss linear; } Thanks for the ideas and at least this problem is solved, Gerry. |

Hi,
I want to use the "Gauss limitedLinear 1" scheme for div((nuEff*dev2(T(grad(U))))) but I get an error in simpleFoam. Whay does this scheme does not work for this term? Quote:
