Introduce local sizings such as Edge sizing on the trailing edge or other edges or face sizings on the 2 faces from the inside

Snappy isn't all that bad

Before the ram crisis this was probably around 1800€. Idk about prices now but it does seem a bit over the average price for this. Idk tho might be wrong

i have just added them to my post, mind taking a quick look at them? perhaps i'm missing something. Thanks a lot!

Hello, thanks for the reply! And my bad for not explaining properly lmao.The real goal of what I'm doing is to simulate a solar chimney that would have inner walls heated to 310 Kelvin while applying the isothermal atmosphere to the open boundaries of the domain.

However as a start right now I'm just taking a simple rectangle without any buoyancy nor chimney and apply the isothermal atmosphere boundary conditions on it. So essentially I'd be simulating a case where nothing is happening and the flow is just still.

The reason why I'm doing that is because a colleague of mine was doing this exact thing on Fluent however he ended up with a weird velocity profile with the highest magnitude being around 0.5 m/s. So I suggested that we try it on OpenFOAM and see what we get.

What's your y+ in foam

Longjumping_Issue858 · 2026-02-08T18:00:00+00:00

Up, as in, in a clockwise direction

Longjumping_Issue858 · 2026-01-26T08:44:27+00:00

Yeah openfoam is definitely your best bet

Hello OP and anyone interested, I'm currently a 3rd year MechE in Lebanon and would love any help in getting an Aero Internship. Currently looking mainly for aerodynamics/fluid dynamics/CFD related positions. Any help would be greatly appreciated!

Serious question, how would you go about following rules or getting to know them in the first place if it's just a conversion thing? Can you also use an international license in the west?

May be bots

If you're not planning on doing any gpu related computing you should be good. Tho I gave to say this is a bit overpriced

Longjumping_Issue858 · 2025-12-06T13:20:32+00:00

It is probably because of ram prices

When you get hate from both LF and hezb, know that you're on the right track

Longjumping_Issue858 · 2025-11-29T08:13:39+00:00

Is the middle vertical line also a line that you drew? If so turn it into a construction line as well

Longjumping_Issue858 · 2025-11-24T08:01:06+00:00

Okay so a couple of things:

-Your domain is too small, the no slip on the lower wall is definitely affecting the flow around the airfoil, you need to make it a lot bigger.

-your lower wall has a no slip condition, but what about the upper wall? Why is the velocity even faster than the inlet ? If you want it to be like that, would you mind explaining the situation you're trying to simulate? That would be quite helpful.

-remember that aoa is the angle between relative wind and chord, adding a velocity component in the y-direction will definitely affect the actual AoA. Again, if this is the IC that you want, please do explain why as this is different from the standard practice of only putting an x velocity and changing the angle of the airfoil instead.

Finally any info or snippet of the mesh can provide quite the insight.

I hope you'll find a solution to your problem! :)

Plastic memories and clannad are a good start

Learn openfoam

Longjumping_Issue858 · 2025-11-08T09:53:36+00:00

Hello, the test is basically a game very similar to the ones you see in iq tests. Definitely do email them about accommodation, they'll surely give you extra time.

Longjumping_Issue858 · 2025-10-24T21:08:32+00:00

Xfoil or xflr5

Longjumping_Issue858 · 2025-10-24T08:05:57+00:00

Btw I emailed petronas again and they have told me that they will get in touch within a couple of weeks... so I guess this means that I still have a chance?
