Hello everybody, i'm a student and new here.

I have a divided 2D body with a wavy surface, in the meshing at the name selections tab i have a problematic wall (aka "exclude_wall") which i do not send to the solver. in the solution at the boundary conditions tab i find the same wall in a different name and with "wall" type.

the analysis type in the geometry is set to "2D", the body is set to "Fluid", the physics preference is set to "CFD" and the solver preference is set to "Fluent", so to that part i got covered, and from here i could not find the solution to my problem.

could someone help me understand how to remove this wall and why dose it enter as a boundry condition from the beginning?

thank you.
