How to obtain sgs TKE in FLUNET udf not in post-processing?
The sgs model I used is dynamic smagorinsky model, I don't know how to call the subgrid dynamic smagorinsky const(Cs) or sgs turbulent viscosity(μsgs) at C side. Someone told me the ksgs=(μsgs/ρ/lsgs)^2, lsgs=min(0.41*C_WALL_DIST,Cs*C_VOLUME^1/3), Cs is not const in dynamic sgs model, Cs can be plotted at FLUENT side, but I want to call it at C side. So μsgs is. If choose the Kinetic-Energy Transport model, the ksgs can be plotted at FLUENT side, but I can't transfer it to C side also. |
