Hi everyone,
I've been succesfuly working with the synthetic eddy method bourndary condition to generate a realistic boundary condition in LES simulation from the LEMOS group at Rostock Uni. If someone is not aware of it, it is called decayingTurbulenceInflowGenerator and works really well for generating turbulent inlets for LES (you can find it here: https://github.com/LEMOS-Rostock/LEMOS-2.4.x). So the thing is, it works like a charm if you only have one inlet. The boundary condition is hard coded to generate turbulence only in the +x or -x direction, so you have to rotate your mesh in such a way that the turbulent inlet you want to use is in that direction. However, I am now simulating a case with two perdendicular inlets (one in the x-direction an the other in the y-direction, something similar like the image attached). So, currently I can only choose to have one of the inlets turbulent while the other has to remain laminar. This is quite bad and I would need to fix it so that both inlets are turbulent. Can anyone provide me with some guidance as to how to do this? I tried compiling a modified version of the LEMOS condition but hard-coding the y direction instead but I was not able to do so. Thank you! |
