Hello Foamers,

I try to run a LES case with buoyantPisoFoam but whatever I do it always returns me this error :

Since there is no issue with RANS tutos, I suppose it is caused by LES, but I do not know where exactly.
Any help would be greatly appreciated

It seems that error happens at this level, in the createFields.h file :

Info<< "Creating field DpDt\n" << endl;
volScalarField DpDt
fvc:: DpDt(surfaceScalarField("phiU", phi/fvc::interpolate(rho)), p)

But I still don't understand how to avoid it ...
Does anyone got the same issue / an idea ?
