Hello FOAMers,
I want to extract turbulence quantities using the solver pisoFoam, particularly the turbulence kinetic energy dissipation (epsilon). To contextualize, i am performing the simulation of a planar jet using the LES model dynamicKEqn from OF5. By reading the dynamicKEqn.H the epsilon is being returned: Code:
177 //- Return sub-grid dissipation rate 178 virtual tmp<volScalarField> epsilon() const; Code:
functions { ... turbulenceFields1 { type turbulenceFields; libs ("libfieldFunctionObjects.so"); field epsilon; writeControl timeStep; writeInterval 1; } } Does anyone have the same problem or know how to solve it? Maybe it is a problem of my OF, i don't know but it is really strange as this quantity should be an easy one to output. Moreover, i want also to extract the dynamic constants of the model (Ce and Ck) and tried without success... |

I ran OF in another machine and the turbulenceFields command worked.
But the question of the Ce and Ck constants still remains! |

I will create a new thread for the dynamic constants of the model.
