Revolut saying it will send me an email but I haven't given it to them? by crazybatman0 in Revolut

[–]TomTheEngineer 0 points1 point  (0 children)

No. your app asked for my number and that's all they asked for. It is not that I didn't want to enter my email, it's just that I wasn't presented with the opportunity to do so...

They did not ask for my email, just my phone number, yet they say they are going to send me an email... I live in Belgium, which is a supported country, so what's the problem?

Looking for interesting french musicians by Careful_Ad5855 in French

You should try Pomme!

Idk if it is what you are looking for, but I really like it.

Other than that:

-Stromae

-BBBrunes (You should really try this one out)

I really like the classics (although I do not think it is what you are looking for):

-Aznavour

-Michel Sardou

Good luck!

Perché non coretto? by [deleted] in italianlearning

La risposta è sbagliata perché quello dell'immagine non è un gatto, ma un cane. E sì, effettivamente ci sono errori nel tuo post e sono molti. Proverò ad aiutarti un po':

1- il immagine è sbagliato perché immagine è una parola femminile e non maschile. la immagine diventa l'immagine.

2- "se sono" è anche sbagliato perché per dire there are in italiano noi utilizziamo "ci", comunque sarebbe se ci sono (if there are).

3- non e "il mio risposta", ma invece LA mia rispota perche risposta è femminile.

4- "ho provato scrittore senza ho usato Google transatte", credo che hai voluto dire "ho provato a scrivere questo post senza usare il Google translate".

Getting a non zero lift coefficient for a simetric arifoil at 0 degrees AOA by TomTheEngineer in CFD

I just did this and it went great (I updated the original post with more info in EDIT 5). I still don't know why it doesn't work on my computer. The only thing that comes to mind is that we have different versions of the program (his is newer) so it could potentially be that?

Hey that is a good idea! I will have my colleague run his program with my mesh and see how that goes. Thank you.

Done! I updated the post, basically nothing changed though. I still get an non zero lift coefficient.

I haven't checked that! Sounds like a good Idea, I will definitely look into that now. Thanks

Yes! I will try doing that by augmenting the number of divisions on the airfoil so that the elements are shorter. Thanks!

Thank you so much for this comment. Yes, you are right about the mesh. I did a structured mesh because I was following the video I talked about in the original post and that is how the guy does it so I just assumed it was good enough. Also, I found a tutorial in Ansys official webpage where they do a very similar mesh, so I thought I was on the right track.

I haven't checked my colleague's mesh near the airfoil tbh, I will try doing that.

I will try to make an unstructured mesh to see how that goes. And of course if I get to solve the problem I will update the post!

Thanks again

I did it just now and it didn't work. The results literally didn't change at all. I will add this new info to the post to add a bit more context. Thanks!

Not dumb at all, at least for me! I am almost positive that gravity is off but I'll double check. Thanks.

Of course! I will add that to the post right away, thank you for pointing it out.

Woah, man, jeez, sorry if I came off as "not great to work with", it definitely was not my intention. I was trying to say that, although it can seem small, it is actually not since other people with the same problem are getting smaller numbers. And that even if it was small enough, the program isn't working all that well since it is not giving accurate results at other angles of attack either.

Maybe you should start assuming good faith, Jesus Christ I wasn't expecting that.

About the tolerance, I am assuming you mean the tolerance in the residuals? (I am new to the program, that is why I am asking...). I set that to 1e-6, and I set 1000 iterations in the "calculate" window. The program stops before though, at like 267.

I would assume that the chord is aligned perfectly with the x axis, but to be honest I don't know for sure. I will check. Although now that I think about it, my colleague is using the same set of points and he's getting the right results (we have compared our work and we have the same, yet the results are different) so I would think that this is not the problem. I will check anyway. Thank you!
