how to solver perturbation equations of navier stokes equations ?1 Attachment(s)
Hi All
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 fvVectorMatrix UperEqn ( fvm::ddt(Uper) + 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. Best Regards |

Hi,
Have you had any chance solving this? |
