Help for implement Anechoic Condition

[josepedro]

Dear forum users,rnrnI want to implement a wall that have a anechoic condition.rnThis wall was presented in this article:rnNon-Reflecting Boundary Conditions for One-Step LBM Simulation of Aeroacoustics – 2006 (Kam)rnrnHow can I find the collide operation in OpenLB?

Hi Jose,rnrncollide operation is situated in src/dynamics/lbHelpers.h but also in the corresponding lbHelpers2D.h and lbHelpers3D.hrnStandard BGK-collision is called:rn bgkCollision()rnrnDid you already found the boundary conditions, like bounce back, in our code?rnrnAlbert

rnrnrnHi, Josepedro,rn Here are all the model supported in OpenLB 0.9. The “”dynamics”” classes are mainly reloaded for collision model, and “”momenta”” for macro parameters model, like density, velocity. You can check the most similar class name to your boundary model to see if it meets your need.rnhttp://pan.baidu.com/s/1kTuA56Z password:0nghrnhttp://pan.baidu.com/s/1bnsjbmJ password:8o48
