Dear Foamers
I'm trying to solve this equation

    gradienteC = fvc::grad(C); 
    dcdx = gradienteC.component(vector::X); 
    Dw0 = turbulence->nu()/Sc;

   fvScalarMatrix depositionEqn
    (
      Fm * rod * fvm::ddt(r1)
     - Dw0 * dcdx
    );

Fm and rod are both constants, and Sc is the Schmidt Number defined as a constant
When i try to run it in my case it give me this error

Anyone knows what means this error? and how can it be solved??

Thanks to all
