This is my geometry file, and I use ideasUnvToFoam to input to my openFoam, this time i use tutorials/interFoam/dambreak/ for my base file.

but my file is too large, so I canot post on here.

this is my geometry:
figure1:https://app.gemoo.com/share/image-an...34073228611584
figure2:https://app.gemoo.com/share/image-an...53043314810880

In my graphic, I want to define the contact surface between the water and air domains as a contact surface (merging two surfaces into one), and define the area marked in red in Figure 2 as a wall surface. How can these steps be achieved in Salome_Meca?

I have tried some attempts on Salome_Meca, after importing into OpenFOAM and entering checkMesh, the result is as follows. I don't think it meets what I want. Could you please provide some suggestions or relevant tutorial video links?

Thank you.
