Can anybody please tell me difference in algorithms of full-way bounce back and half-way bounce back boundary conditions in LBM. I want to study their effect of convergence. Thanks in Advance!
Although bounce back BC's are simple, but implementing them in a right manner makes it complicated depending on the geometry of one's problem. So I suggest that read some concise and explanatory papers in this field. I send you one and hope that it would be helpful. But briefly I can say that if you update your BC before streaming step , so you are using half way BB. and if you updating BC before collision step you are using full way BB.
