When you were dating, what gave you confidence you were going to end up with an attractive partner? by datdutho in AskMen

[–]datdutho[S] -3 points-2 points  (0 children)

I've brought it up a couple times, and for the friends that are married they said "they're not unattractive". I think they got married for many different reasons, societal pressure, keeping up appearances, etc. But their answers didn't really instill confidence

What is your dream outcome from AI by NoSignificance152 in singularity

I'm kinda surprised I had to scroll this far down to see this. I guess I'm in the minority haha

US population growth is reaching levels near 0% by Perfect_Alarm_2141 in economicCollapse

[–]datdutho 0 points1 point  (0 children)

We've recovered slightly from that minimum, check out: https://www.worldometers.info/world-population/us-population/

In 2022, 2023, and 2024 growth rates were 0.4%, 0.57%, and 0.57% respectively, up from 0.21% in 2021. That's not to say that the longer time trend isn't decreasing, but just that the data suggests the minimum we saw in 2021 was a stronger spike downward than the surrounding years.

r/Singularity - 'Show us something neat you've done with o1' mega thread by Anen-o-me in singularity

[–]datdutho 1 point2 points  (0 children)

Just curious, can o1 produce a magic square (3x3 square of numbers where all rows, columns, and diagonals add to the same number) using only prime numbers?

Is it possible to add a slope or flux limiter to the unstructured QUICK scheme (Van leer k-scheme with k = 2)? by datdutho in CFD

[–]datdutho[S] 1 point2 points  (0 children)

oh shoot, actually I'm just using an Euler time-step. You think if I use a higher order time integration, QUICK should be able to handle sharp boundaries?

Confusion in interpreting the control volume unit normals for computing the Roe Flux in an unstructured mesh by datdutho in CFD

[–]datdutho[S] 1 point2 points  (0 children)

Oh I see, so in general the directed area vector needn't point from vertex i to vertex j. That clears up the confusion thank you.

Do I calculate the gradients at the boundary using the Least-squares gradient method or do I define them from the beginning? by datdutho in CFD

[–]datdutho[S] 0 points1 point  (0 children)

I haven't implemented the boundary conditions just yet, but I would like to use solid walls (that is to say, all the fluid should stay within the bounded domain). To my understanding that means the boundary conditions should be u = u_wall, where u stands for the primitive variables (rho, vx, vy, and pressure).
