Any other condition you must define yourself via weak conditions (if possible, but as many things are possible in COMSOL why not try) -- Good luck Ivar Melanie Pigeon Send Private Message Flag post as spam Posted: 1 decade ago How exactly do I set up this flow continuity? Can I...
Note: This discussion is about an older version of the COMSOL Multiphysics® click here Niall Mangan Send Private MessageFlag post as spam Hello, I would like to model a semiconductor with 3D periodic structures (~100 nm in length scale). I would like to make one unit cell in 3D and ...
I am trying to simulate using the Rf module TM in 2D an infinite structure in the x dimension. (comsol 3.3) Therefore I'm getting used to the periodic boundary conditions and the floquet bloch phase shift. I simplified my problem to a very simple one: a plane wave propagating with wave...
(light, microwaves) incident upon periodic structures, such as diffraction gratings, metamaterials, or frequency selective surfaces. This can be done using the RF or Wave Optics modules from the COMSOL product suite. Both modules provide Floquet periodic boundary conditions and periodic ports and ...
I do not think that specifying the wall shear stress is appropriate, especially for LES. You would need to know the local wall shear stress everywhere on the walls and apply that as a boundary condition through UDF (which means you would have to already know what the flow looks like, whic...
