How to implement an adiabatic boundary

[Leaf]

hi, guys,rn Has anyone tried to build an adiabatic boundary in OpenLB? If you achieved, could you plz give me some advisement on the dynamic and momenta class selection for adiabatic boundary? Thanks.rn What’s more, is there anyone interested in the transformation of units between LBM and physical world? I hope we can do some cooperation in the derivation of the switching strategy. Of course, it would be grateful if you can directly offer suggestion on this topic. rn My e-mail is openlb12@163.com. Thanks again.

Hi openlb12,rnrnI am currently also working in the same direction. For the adiabatic boundary I have been using the bounce-back boundary, since the lattice descriptor for the thermal variables only has velocities in perpendicular and parallel directions to the wall (based on the assumption that your boundaries are aligned with the coordinate system). I hope it’s useful.rnrnRegards, marcanyada

rnrnHey, Marcanyada,rn Thank you for your reply. If possible, could you send me an email, so we can discuss efficiently and timely. What’s more, about the bounce-back boundary, which boundary dynamic class do you select? Could you give me your boundary code? rnrnHere is my email address, openlb12@163.com.
