gusfrota is on a distinguished road
I'm trying to recreate an experiment with Ansys Fluent. It's a simple problem of a cylinder and a flow passing through it. The questions I'm facing are the following:

1) The experiments uses a Ramp Up for the flow velocity of " ramp-up rate a = 2 E-04 m/(s^-2)
2) Kinematic viscosity of water = 10^6 mē/s. I believe Fluent asks for dynamic viscosity since the density is also needed. So it's just a math question

I saw different questions from other users, it seems that I need to input a profile for the velocity or a compiled file. But I'm a beginner and also, this is for my Graduation Teses. If someone could help me, I'll be immensely grateful.


The experiment i'm using as base is from Z.P.Zang and F.P. Gao
