Hello Foamers:

As a beginner of Openfoam, I'm doing a project to simulate the turbulence phanomenen in neck of a Heimholz resonator with different compressible LES Model. The mesh formed in a wegde with axial symmetric BC. Cases work well with compressible oneEqEddy and Smagorinsky LES modeles. But when I turn to the homogeneousDynOneEqEddy Model(which seems to be the only dynamic LES Model available in compressible cases), simulation breaks before the first step with the output like:
Selecting turbulence model type LESModel
Selecting LES turbulence model homogeneousDynOneEqEddy
Selecting LES delta type cubeRootVol
--> FOAM Warning :
From function cubeRootVolDelta::calcDelta()
in file cubeRootVolDelta/cubeRootVolDelta.C at line 52
Case is 2D, LES is not strictly applicable

I've also tried a 3-D geometry without changing the BC(that may cause some problem), but the output error was the same. I think the problem exists by calculating the coefficient number of c_k or c_e, but have no idea how to correct it.
I also wonder if wall functions like the one I used (compressible::kqRWallFunction) here is available for dynamic LESmodels.I've put my LESPropeties and k BC here. Can anyone give some advise about this?

With regards

Get rid of this:

SmagorinskyCoeffs
{
ce 1.05;
ck 0.07;
}

then it will work.

Can you upload the full case?

@WilliamHill Why do you think it'll work if it is done so?

[WilliamHill]

I use different solver XiFoam with LesProperties which SmagorinskyCoeffs was removed from. It works. If it doesnt work, the problem must have sth to do with other setup, but not Lesproperties.
