how to solver perturbation equations of navier stokes equations ?
I want to solve perturbation equation with OF. I attached these equations.
but I don't know how to calculate the convection term. I used the bellow equation
+ fvc::grad(U)& Uper
+ fvc::grad(Uper)& U
- fvc::laplacian(nu, Uper)
solve(UperEqn == -fvc::grad(pper));
but OF debug encounter error for calculating
fvc::grad(U)& Uper and fvc::grad(Uper)& U
I would be very appreciative if someone could point me in the right direction to get this model running.
Have you had any chance solving this?
