Fsi
 

Hello!!

I am solving a FSI problem. In this regard, I used a realisable k-epsilon model for solving the problem.

In ANSYS Fluent solver, METHODS section which are all diffusion terms and which are all convection terms? so that I can specify the methods to them as per the journal I referred. I have also attached the screen shot of the journal image with this.

Thank You

Discretization
 

The mention in the journal does not imply the available choices. Diffusion terms in Fluent are always discretized using central-difference scheme and, consequently, is second-order accurate. The only option related to diffusion is choice of gradient calculation and limiters. The discretization schemes available under methods are all relevant to convection terms to determine the flux at the upstream faces or for pressure interpolation.
