[Nek5000-users] double mesh ?

[nek5000-users at lists.mcs.anl.gov]

Hi

i am quite new, so i’m sorry if i’m getting things wrong.

I am trying to simulate a turbulent channel flow, with a passive scalar. 
in the streamwise direction, i would like to impose periodic boundary conditions for the flow, and non-periodic for the scalar.
in fact the scalar has a point source near the inlet, and i want to see how that develops downstream. 

as far as i understand this is not supported by nek5000, because the last mesh point is identified with the first mesh point when periodic BC are imposed.
correct ?

my question is : could i define two meshes, one for the scalar and one for the velocity ?

thanks a lot for your help !!!
