[Validation: marine] Hydrofoil NACA 0024
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

.CAS file
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.

UDF: unsteady inlet velocity error...
2 Attachment(s)
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?
