[Nek5000-users] Passive Scalar Initialization

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

Hi,

I want to start solving the passive scalar equation after the  
background flow field has reached certain characteristics. Is it  
possible to defer the solution of the passive scalar and then  
initialize it at sometime t>0? In this case, should I include the  
passive scalar boundary condition data in the rea and usr files from  
the beginning?

Thanks for your help.

Regards,
Alireza
