[Nek5000-users] Heat/passive scalar solver - Helmholtz

Dear Neks,

I am a little confused by the setup in the rea file to run a simulation with a constant cfl. My understanding (from the Nek5000 archives) is that by setting p012 to a positive value in the rea file, it should be sufficient to ensure a constant cfl condition during the run. When I do so, my time step is constant and thus my cfl varies. 

I tried to set p012 to a positive value in different rea file from the examples directory but none of them yield a constant cfl during the run.

If someone has an answer to this problem I would really appreciate the help.

Thanks,
Marco
