Hello All,
I am using the buoyanBoussineqPimpleFoam solver for one of my project. It works perfectly fine with flat bed (slope=0), but when I put a small slope that means I add x component in 'g' field, the solution becomes somewhat unstable at later time. I am using dynamic Smagorinsky LES turbulence model, bounded backward time integration scheme and SFCD divergence scheme. Any body experienced similar problem with slope? I would appreciate any feedback. MMMN |
