Hello to all,
i want to define inlet boundary condition for rearward facing step and using Driver and Sigmiller data. Not only for velocity, it also need inlet B.C for "U Prime 2" which is a tensor with 6 value for each node. (u'2,v'2,w'2,u'v',u'w',v'w')

The problem is how and where should it be defined. i haven't seen anywhere in tutorial files that in 0 folder has been defined.

The order of entries in U'2 should be (u'2 u'v' u'w' v'2 v'w' w'2)

Default "k" as input or "LRR"

Use LRR model.

If k-epsilon is must, then change the tensor into a scalar 'k' and feed as input.
(As I guess only way to feed this tensor data is by using 'k')
