[Nektar-users] Solve scalar transport equation along with Incompressible Navier Stokes

Hello all, I am trying to study scalar mixing from a jet. I can use the incompressible Navier Stokes solver to get the velocity at every time step. I am thinking of calling the advection-diffusion solver from the Navier Stokes solver every time step and solve for the scalar mixing. I was wondering if there is any other easier approach? Is there any example that I can look into? I greatly appreciate any help regarding this problem Thank you, Siddarth
