Unsteady ramp inlet velocity
 

Hello,



I was wondering if it's possible to add a ramp inlet velocity to an unsteady simulation.

I would like for the velocity to grow for the first 2s as a ramp.



Thank you for your help,



Alice

Hi there, "Laminar Backward-facing Step" tutorial might be helpful.

Hi,


From the code it looks like the method of prescribing inlet profiles is possible for each time step. In the mentioned tutorial https://su2code.github.io/tutorials/Inc_Laminar_Step/ it is done for a steady state simulation.


For unsteady you would add a 'inlet_filename' + '_00000.dat' (+ _00001.dat and so on) extension that represent the time iteration. so one inlet file is loaded each timestep. I recommend putting those in an extra folder and then INLET_FILENAME= folder/inlet_filename in the config to not clutter everything ;)

Not really the most elegant way and requires a bit of (most likely python) scripting but it is the most flexibel option imo.



hope that helps :)



Cheers, Tobi
