Now, I think that it is not possible to change TM (wall multiplier) for scalar !!!
It would be better if I explain what I have done ...
1/ I have changed the TM value for the velocity : this works since it has an effect on the shape of velocity distribution U(y)
2/ I did the same for scalar => no effect at all.
When I use GETSCA, CFX returns ISC=1 and when testing with IEQN, it changes the velocity'S TM value.
So I've made ISC1=28 (1st scalar equation, when there is no other scalar such as mass fraction) and then compare with IEQN ===> doing such make (I think) the scalar's TM modification. BUT, while making TM varying from 1e-10 to 1e10 I saw no effect at all on scalar's distribution (scalar(y)).
(TM=0 => severe fortan error ;-)
Scalar's distribution response is fortunately affected when I change boundary conditions value (I mean A,B,C in the command file).
I think that I have misunderstood something with wall function concept in CFX ? So if someone could help me, I would like to know where I am mistaking ?
Thanks in advance
