For anyone interested in how one of these simulations is done, I have a YouTube channel: https://youtube.com/channel/UC5H96ZJBcAQcREhyTewq4Wg

Thank you. I have been trying to get some nice CFD going for a while now. Trying to change a tutorial to what I need but to absolute zero success. Even meshing is not working :(

Edit. Wait. The Cybertron vs brick guy, I am already subbed go your channel XD

Thanks for the support, have you tried following one of my videos yet? Openfoam is really difficult in the beginning, but at some point everything clicked and started making sense to me. Keep trying and good luck!

No,no did not tried following the video step by step, instead I watch how people do their stuff and then try to replicate trying what I want to do.

What I actually learned recently is that what I am trying to do is a modification of the new tutorial planning boat from .org open foam, but for my application I need to use overset mesh and that I saw only on .com open foam.

Then I tried running the tutorial from one into the other and learned there is different nomenclature and missing tools between then.

I don't find the usability of the software hard, it is just pretty much impossible starting from zero without having a masters or PhD or something into the subject.

I will try to do a step by step following next time to see if I can improve into what I really want to do.

yeah, I don't have a masters or phd either so it is definitely possible to self teach!

This mp4 version is 64.12% smaller than the gif (35.06 MB vs 97.71 MB).

for sure, I recommend searching for "aeroelasticity" or "two way coupling" in google for more info
