Thanks,
You mean its a scalar rite? Actually its a simple version of the regular one. Its an equation of a turbulence model. "Partialaveragebased equations of incompressible turbulent flow" I attach a image. This equation is tough to handle. Right now I have no idea how to solve this equation.

I think is a simbolic power of the operator l.Grad therefore it must be applied n times on the function
