Benchyyyyyyy

Not the benchy. 😁

There is some stutter in the motion blur which makes me think this could be done in Paraview, too... The smooth looping of the animation is very impressive in any case!

benchy does not always sink though, it can capsize too 😂

What's the utility of this kind of rendering of CFD results?

For pure results analysis, none. For communication: producing material easily understandable by general public. We often have visitors at the office who have no science background and they usually don't understand a single thing if you start showing some velocity/pressure fields or graphs. We show this case a lot to explain what we do with CFD (aka: trying to compute how things behave in real life) For marketing: our clients usually need our help to develop a product and they are interested in good looking visuals they can use for marketing purpose, to communicate about their development process, performance of their product, etc (and once again, if the product targets general public, you need something good looking and easy to understand)

A friend helped me for a mesh once, that I was supposed to use for a presentation. I am glad I checked the name before since it was the same joke on the title, ready to be displayed at a meeting 😂

I once complained to a coworker that diffusion was eating all my turbulence noodles. They were more than a little confused...

But nice TS-waves

How did you call me??!!!

When the Schlichting hits, stability quits

hahaha, you made me chuckle!

Nah seems legit just the coloring is a bit off 😄 normally its cool on top and hot on bottom, here it seems viridis on both

maybe it seems a bit off to you because you did it in 3D and 2D is kinda different because of the inverse energy cascade

I think I just don't know how to interpret the colors properly

I'm sure it makes sense, it just doesn't to my eyes lol

yeah that makes a huge difference, at some point all vortices merge and the simulation gets boring

unfortunately i don't have the exaflop at hand required for the 3d simulation at the same resolution xD

nice work🤝

Not very colourful and not done with openFoam but I thought I’d share this small video showing laser welding of stainless steel https://cdn.discordapp.com/attachments/978933121829445632/1387703306851451022/test_RT2.mov?ex=685e4eea&is=685cfd6a&hm=7c3cb692968cb2175bcae6e077e33c7a383de94525221edcc9731c512f08059e&

it looks not too fancy, but quite happy with it. automatic quad mesh simplification and clean up: from left to the right, i am removing the nodes with different valences (nodes that have different number of neighbors to 4) to a minimum https://cdn.discordapp.com/attachments/978933121829445632/1392091207877787751/image.png?ex=686e4577&is=686cf3f7&hm=3f6805603fe9eb842460cae4af85c32aaaa686a23bd0ca50bbd7e48c35481c14&

What did you simulate this with if you don't mind my asking.

I used Flow3D Weld to simulate this, post process with paraview

This is a thing of beauty https://cdn.discordapp.com/attachments/978933121829445632/1394785281785331833/1752562779811.1752613055081.publer.com.mov?ex=68781285&is=6876c105&hm=f940b0a19a763ce91796d644eadc659bcfeba8e33d878b70607dda9ef92b6e6b&

There’s more, feels like an 18+ website😂

Someone posted this on LinkedIn. Wanted to see f1 car doing mach 5 😭 https://cdn.discordapp.com/attachments/978933121829445632/1394857667167654019/AISelect_20250715_100214_LinkedIn-ezgif.com-optimize.gif?ex=687855ef&is=6877046f&hm=7ac829eac68679e992726f4a04958ff53de11d71e59c10d14a3dbe3e79901289&

Not even tom cruise could survive that

nice! what do you look for in that type of sim?

i would say more like SSJ3 than mach 5 🤣
