Hi I am Fabian a new OpenFoam user,
i try to simulate a flow around a circular cylinder at moderate Re numbers. around 200-300. Due to transition i want to use a dynamic LES model, but i am always getting a dimension error, with all available dyn solvers.
I read a lot of threads here and i can not get a solution for it.
For example with the dynMixed Smagorinsky.
--> FOAM FATAL ERROR : LHS and RHS of + have different dimensions
dimensions : [0 1 -1 0 0 0 0] + [0 2 -2 0 0 0 0]

From function operator+(const dimensionSet& ds1, const dimensionSet& ds2)
in file dimensionSet/dimensionSet.C at line 379.

I would be very happy if somebody could help me.
Thanks Fabian
