Default Velocity Inlet & LRN
Posts: n/a
1. How to set the arbitary velocity inlet B.C, i.e., the non-uniform velocity? Anyone who has some ideas is appreciated.

2. By the way, those who has used the Low-Reynolds-Number (LRN) k-e turbulence models. Could you tell me what is the corresponding references for (0) Abid? Is it k-t model? I found all references but this.

Thanks a lot!

1) For this you can write a udf with random number genarator in C. May be multiply each random number with some constant to get higher velocity. Use this macro and hook at the inlet, I suppose.
