Reply To: BounceBack boundary


Hello Adian,

Does the class BounceBack in olb-1.4 means full-way bounce back? I am running transient cases, and I learned that half-way bounce back is more accurate than full-way in time. so I wonder how to implement it in openlb.

since you have mentioned postprocessor previously, then I tried with that but it didn’t work well. Could you elaborate how to implement it? Thank you in advance.

Here is my plan, since half-way only change streaming process, I define walls with bulk dynamics and use a postprocessor to make modifications, which basically implement bounce-back rules according to their directions.
