Help setting up a 2D multiphase simulation of an airfoil
 

Hi everyone,
this is my first post so hello to all members of the group.
I am a beginner in the use of STAR CCM+ and I would like to set up a 2D simulation of a NACA 0012 profile in the water to evaluate the behavior of the wave it creates during navigation by repeating Duncan's experiment. (thus using the VOF model).
Unfortunately, from what I understand, the VOF (FLAT) Wave model is only usable in 3D. Which model should I use?
Thank you

I don't know why you're assuming we're all familiar with Duncan and his experiment. A reference would help understand what you're trying to do.

Sorry, I thought I attached some documentation.
Let me try to clarify: The experiment involves calculating the CL and Cd of a NACA0012 profile in a multifluid domain at a specific Reynolds value. I've already replicated the experiment using Numeca Fine/Marine software, and in the attached image, you can see the mesh I used. The blue line on the mesh represents the free surface.

However, to replicate the experiment using STAR CCM+, I need to use the VOF Wave model and the Trimming mesher to refine the free surface, both of which are only available in 3D. Therefore, I need to create a 2D pseudo-mesh with a single cell in the Z direction (which is still 3D) like the one I used in Numeca. Can you suggest how to achieve this for the entire domain?

If you actually have 3D mesh (made in Numeca) - then you don't need Trimmr Mesher and you can:

As for the mesh refinement - Adaptive Mesh Refinement (AMR) can help you a lot.
