akidess will become famous soon enough
It means that you are trying to solve for two variables within one equation.

Thanks. That is clear . However a formulation like below ,
fvScalarMatrix hEqn
        fvm::ddt(rho, h)
      + fvm::div(phi, h)
      - fvm::laplacian(turbulence->alphaEff(), h)
assumes constant k . How does one program without the constant k assumption ?
