Hi I am using denseParticleFoam solver to simulate 2 phase flows and I want to calculate th wallshearStress, using the denseParticleFoam -postProcess -func wallShearStress but whenever I start I get this error

    }*/
    }

and the error i get is

Starting time loop

wallShearStress wallShearStress:

--> FOAM FATAL ERROR: 
Unable to find turbulence model in the database

    From function virtual bool Foam::functionObjects::wallShearStress::execute()
    in file wallShearStress/wallShearStress.C at line 210.

Does anyone know how to fix this issue?

Thanks

How do you set the turbulence model?

What is your constant/turbulenceModel or similar?

Laminar flow simulation and viscosity is constant
