Hi Thibaut, I think the issue here is that Physical Surface is just a grouping function, it doesn't perform a boolean operation on the surfaces like what you might expect.
Take a look at the modified file attached. It saves the line loops of the beams which are on the channel face and then uses them to create a plane surface afterwards with the line loops subtracted (so this surface has holes). (I looked at the 2D surfaces here, it doesn't generate the 3D mesh properly because of the stuff commented out at the bottom but I think that should be easily fixed).
Regards,
Dave

For my Fluid Mechanics research project, I have to run simulations on a channel with a hairy coating on the bottom plate. I model these with micro-beams. Thus, I have created a "Beam" function that enable to create little beams on the bottom plate. My problem is that I cannot manage to merge the bottom surfaces of the beams and the bottom surface of the channel in one physical surface... I hope you can help/advise.
You will find my code attached to this email.
Thanks!
Thibaut
