Hi, you will put the pressure gradient into userf (e.g. ffz=1.). In this way you can specify the expected Re_tau of your simulation (together with Re). Philipp On 2018-04-18 10:34, [email protected] wrote:

Dear Nekers,

I post last time regarding pressure gradient in the pipe flow. Is there anyone know how to do the single phase pipe flow keeping pressure gradient rather than flow rate?

Best wishes,

Zhai
