@JJDreese The winner was in Illinois, no?

[Zach Davis 🚀 @RcktMan77]

@Klono_King @elonmusk No, he could have given $5 billion to 8 people, or he could have given $5 to 8 billion people. Time to repeat 3rd grade…

…unless Will Smith’s wife’s boyfriend happens to be Chris Rock.

All I know is that Will Smith's wife's boyfriend must be so grateful that he stood up for their woman

Great #sunset this evening in DTLA…

I should probably stop doing this…

@JJDreese Just across the 405 at NGC

See you in Los Angeles 👋

I am making these tweets to explain in one place some analysis that was done last night.
1 - I was asked offline about doing Benford's on election data. I explained that this is common and a useful way to detect anomalies in data that are driven by artificial process (e.g. fraud)

@libbala @RealJamesWoods @milesfisher I think it was a reference to his role in Born on the 4th of July…

Yosemite Sam is definitely not going to make the cut then… #ElmerFudd

I don’t believe this belongs to @FTW_Caro… Where’s all of the Star Wars decorations? I’m thinking this must be an imposter.

Thanks for the mention! Meshing from home is fun! 😀

[Zach Davis 🚀 @RcktMan77]

As an addendum: Why you should prefer hexahedra, rather than tetrahedra if the geometry you’re meshing permits… #SimulationFriday (Throwback) #ApologiesForTheBadColorbar https://t.co/IRD61d0eKn

[Zach Davis 🚀 @RcktMan77]

I’m pretty sure we explored this with the ONERA M6 wing with structured, mixed element unstructured, and a voxel mesh stitched to a boundary layer resolved T-Rex nearbody mesh. Tetrahedra showed more dissipation of flow features like shocks and wakes. Not surprised.

Who else is surprised by the overwhelming popularity of block structured grids? Thoughts on why? Mesh Type Survey Results, Part 1 https://t.co/OHYL9kWeyc

@JJDreese Interesting. I heard that insurance companies will move to increase the number of those employed in their claim denials department by an equal amount, providers will still struggle to get paid, and health care costs will continue to rise for all…

Jet engine designers are moving towards higher bypass ratio designs to help reduce noise around airports. This leads to larger intake diameters; thereby, reducing ground clearance and increasing the likelihood of vortex and debris ingestion as simulated here. @aiaa #PAW05
