Default Using results form previous run as inlet condition

Hi Everyone,

For my simulation, I'm trying to use data (velocity profile at outlet) for a previous simulation file as input data for the new one.

I have followed the procedure :

1. Export outlet velocity profile to a csv file in post.

2. Initialise this profile data in pre & use it for your boundary condition.

That's where start my problem. As I'm using SST model for turbulence, I need to specify a turbulence level at the Inlet. But I could find a way to use my data for that.

Is it a way to overcome this issue? all suggestions are welcome.

Thanks.

(Sorry for my english)

just pick the steady-state results in the solver and voila... that's it

Hi Lauren,

Go back to Post and export the profile again. This time choose "Custom" for the profile type and pick the variables you need

Momentum: Velocity and/or Total Pressure Energy: Temperature, Total Temperature or Enthalpy Turbulence: Turbulence Eddy Frequency (or Dissipation) and Turbulence Kinetic Energy

At your inlet, set the turbulence option to "k and Omega" if you have Turbulence Eddy Frequency, or "k and Epsilon" if you have Turbulence Eddy Dissipation.
