Hi all,
I would like to do a LES simulation for a tidal current (with a 5% turbulence intensity). The tidal current will go from 0.25 m/s and to -0.25 m/s ("-" means opposite direction).

I tried use the turbulentInlet type inlet condition, and find that this type seems not support time-dependent velocity input.

I tried like this:

    left
    {
        type               turbulentInlet;
        fluctuationScale  (0.05 0.05 0.05);
        referenceField    uniformValue table
          ((0 (0.25 0 0))
          (10800 (0.0 0 0))
           (21600 (-0.25 0 0))
         );
    }

It gives errors as:


--> FOAM FATAL IO ERROR: (openfoam-2012)
Expected keyword 'uniform' or 'nonuniform', found uniformValue



Could anyone give me some advice for this kind of simulations?





Best regards,
H

This sounds like something that code stream might be able to do.

There is a good tutorial on how to do similar things in of9 in this video tutorial series (see section 7) https://invidious.snopyta.org/playli...mDChejiwm846Wl. Here is the same playlist here if you prefer the Youtube website https://www.youtube.com/playlist?lis...mDChejiwm846Wl.

In the website for these tutorial you can also find the examples shown in the videos such that you can copy-paste and edit the to suit your problem.
