[Validation: marine] Hydrofoil NACA 0024

axpl · July 28, 2009, 08:41

I'm starting my thesis in marine CFD and I need to validate Fluent code with Hydrofoil NACA 0024 with this exp data.
Here (pdf file) I found a tutorial to setup the problem, unfortunatly I haven't found mesh file so I done it by myself: my domain is a box with NACA at center (it's a full model, I haven't use symmetry). BC are: p-inlet-upstream, p-inlet-side-1, p-inlet-side2, p-outlet-exit, sym-bottom, sym-top, wall-wing.
I following the tutorial but I see only one phase.
Can someone help me to setup this problem correctly?

Syncerely, Alex.

there should be two phases, as defined in pages 3 & 4 of the tutorial. primary phase: air, secondary phase: water

If you want check my run, here I post *.cas file (approx 60MB). Actually I can't yet understand where is my error but I suppose in boundary condition.

Sincerely, Alex

PS: someone can tell me where can I found "sp_naca0024_hf.msh" file? So I can compare BC with mine.

Solving my last problem patching all the water volume (see first post), now I'm setting an unsteady run but after 10 time step (0.005 sec each) I receive an alert of reverse flow on inlet, but only when I try to create a ramp velocity inlet via UDF; if I set a costant initial condition I never receive error. Someone can HELP me?
