How to create 2D meshes for CFD analysis (1 Element across thickness)

hr_nt · November 15, 2022, 23:24

Greetings to all !
I wish to recreate the results from the 2D zero pressure gradient flat plate case described here. I am using OpenFOAM as my solver and thus I have to create a mesh that has 1 cell across the thickness in order to simulate a 2D case. However I am not able to do this in salome. I have tried automatic hypothesis for tetrahedrals and hexahedrals and in both I end up with multiple cells across the thickness. I am really stuck on how to apply one cell restriction across the thickness of the domain. I would really like to get some clarity/tips on this.
