Dear All,
I am currently working on simulation for 2D square cylinder with Re=50000. I am trying to use LES with WALE SGS. I used the setup in the case "channel 395" in tutorial to build my own case, unfortunately I have been using openFoam for 3 months only, so I have a question regarding the data in the "0" folder inside this case: are they related to the WALE model? i.e can I use different setup for the variables inside this folder like ( P,U,K,B,..etc) from another model like Smagorinsky? the reason for that is related to the nature of this tutorial,"channel 395", for example the variable "k" is filled with data like shown below:

/*--------------------------------*- C++ -*----------------------------------*\

location "0";
object k;
}

Which I could not understand how to use my data in this file . and I saw that other LES tutorial is much easier to work with it when it come to the variables inside the "0" folder.

So sorry for this long questions , I hope some one have any advice.

Bashar

Hi Bashar,

I am facing the same thing. How you resolved this issue? did you get the idea for obtaining these non-uniform internal fields?
