Great video(s)!

If you use e.g. the LES turbulence model WALE you have to add this to your controlDict to let OpenFOAM (here Version v1912) write out k_sgs (denoted as k or turbulenceProperties:k in the code) for you.

Here also U prime2Mean is calculated to allow the determination of k_res / k_sgs as well.

functions
{

    turbulenceFields1
    {

        type        turbulenceFields;
        libs        ("libfieldFunctionObjects.so");


        // Either field or fields entries

        fields                  (k); 

        enabled                 true;

        writeControl            writeTime;

        executeControl          timeStep;

        executeInterval         1;

    }

    fieldAverage1
    {
        type            fieldAverage;
        libs            (fieldFunctionObjects);
        writeControl    writeTime;

        fields
        (
            U
            {
                mean        on;
                prime2Mean  on;
                base        time;
            }

            turbulenceProperties:k
            {
                mean        on;
                prime2Mean  off;
                base        time;
            }


        );
}

Very helpful, please keep the LES series coming. Also DES would be an interesting topic!

@EngLhag

Can I dream on a DNS lecture as well? Best CFD YouTube channel by far.

@ankitdave9193

Thank you for detailed explanation on LES, love to hear more on LES. It would be good to hear from you on DES as well.

@professionalprocrastinator8103

I have to say, your contribution is vital for the students of a rather niche scientific domain! I never expected such quality content for a subject that relatively few people choose to study, but I'm glad you exist :)

@MattIannacci

Being relatively new to CFD as a mid-career engineer,  your videos have been INCREDIBLY helpful, and BEYOND valuable.  Thank you!

@kmkchari

It is a practical LES course. I really appreciate your time and energy in making these videos.

@prakashthirunavukkarasu29

"I know that you are going to find this talk extremely useful", you actually mean it man! 
I would like to request you to give a talk on adaptive mesh refinement and more on LES too. Thank you!

@maxsepulveda7441

I find your content really helpful and straightforward. I really appreciate this type of content

@manthanparekh8703

Great explanation. I have a tiny suggestion, that along or after the explanation of the simulation, you can also show the CFD code in OpenFoam or just share the Case file of your simulation, so that we can use it as a reference when we are diving deeper into the concept or simulation. 
Thank you and please continue this series.

@MrDaDolix

Thank you Aidan, your comprehensible presentations of various CFD topics don´t stop to amaze me! My notebook is getting filled out pretty fast every time you upload a new video 😂

@vimalkotak6255

Great explanation. Best  lecture series for CFD

@ghebat4716

techncally my master degree professor owes u his salary because i understood literally evertyhing about LES from this videos and zero from his lectures. Super Thank YOU!

@alexholguino7245

I like these talks, please continue doing them.

@slim590

I find these series of LES very enjoyable and useful. thank you

@kiemnguyen961

Great Videos!!! I watched it over and over, and every time i do that, i understand it more. Thank you millions time:))

@cheikhnatalebmoustaph43

DES would be perfect ! Thank you again for the amazing quality you're giving. I am still wondering how can someone dislike this video ? hahaha

@abhishekgoyal5568

great lecture on how to get started with LES. Would highly recommend it!!

@zakariaemaatallah4708

Thank you M. Aiden for these structural details of the CFD domain

@olamilekanbanjo5609

Thanks for a very articulate explanation and a great video! Your videos are excellent introduction as well as review of CFD concepts. 
Yes, let's continue with the LES series. DES would also be nice. 
Thanks again.
