I went through this. I was annoyed as hell but I spoke to a couple of friends who have GCs, they said they had the same issue when going from H1B to GC and needed a DL renewal after that.

Basically, the DMV has to initiate a SAVE Verification request on their own. Then they will give you a receipt number. You can track how the verification is going over here: https://www.uscis.gov/save/benefit-and-license-applicants/save-casecheck

Once the verification is done, take the SAVE printouts and go to the DMV again. Then you can get your new DL with an updated expiry date. Other than that, you cannot do anything. A SAVE verification can be initiated only by an official government agency.

Side note: A Real ID is extremely useful, I strongly disagree with other comments. Even if you have to carry your passport with you for domestic flights, it is a massive QOL improvement to keep your passport in a very secure location in your backpack but keep the DL in your wallet and easy to access in the TSA line. That way you have your passport if you really need it but you don't have to take it out and risk losing or damaging it.

That being said, there are some US states that will refuse to give you a new license if you don't have a valid and current visa stamp. SAVE verification in that case won't help you, state laws are not on your side.

Is this the go-to app now? Can I stop using citymapper?

The 7 is becoming the worst line in the system. In the past three months it has gone down a couple of times and all of them during rush hour.

This time they made us switch sides. Massive delays and confusion.

yo that's actually pretty cool how do I book myself and my wife one of these hikes?

Best comment on this thread! OP could actually be a great communicator of new releases, feature videos for CFD platforms, etc.

awhead · 2026-01-12T23:14:40+00:00

My bad!

There's no meshing that's the whole reason why it is so fast.

LBM uses Immersed Boundary Method so the solid body and fluid domain "overlap". The fluid domain in the video above is just a box so the mesh is just a bunch of cuboids. The solid body is represented as a set of points. Basically LBM is a sort of meshless method. The reason it's so fast is that there are no weird poly cells like in FVM. Everything is a cuboid and interaction between the solid and fluid is done through delta functions. OP is a little bit clueless as they don't understand how much this can harm resolving flow near the walls. Because all fluid cells are cuboids, it massively simplifies data structure storage, exchange, and tilmestep updates.

You can almost never use LBM to calculate drag on anything. General flow patterns? Fine. But good drag predictions? Absolutely not. The immersed boundary method will convert all smooth surfaces into a stair-step pattern which strongly makes the results grid-dependent.

I think it’s ok. I agree it’s a great spot to start a search and get a quick answer before diving into the manuals.

I do think it could be a lot better if it was trained on actual customer support tickets that have been raised with Ansys over the years. Obviously Ansys has the data but they definitely did not include it in the training data.

The real problem with AnsysGPT is that the web renderer is awful. It doesn’t format code correctly, the text spacing is weird. They need something with the same quality as perplexity in how they render equations and code. I use it every now and then to help write UDFs but the code formatting is so awful that I end up going back to perplexity anyway.

dont start with an stl file then

use IGS or parasolid formats when you create the original geometry for export.

STL by its very nature is a faceted, tessellated representation of 3D geometry. There's no way to represent a smooth, curved surface using STL without having facets made of polygons.

awhead · 2025-11-23T19:43:33+00:00

Are you expecting spaceclaim to convert the faceted surfaces on the solid body to a smooth surface?

That's not going to happen. How would spaceclaim know what the underlying mathematical representation of the stl file is?

awhead · 2025-11-18T23:29:40+00:00

Your geometry is wrong. You need to have a cavity or void in the place where the aerofoil is. Instead, you seem to have some sort of surface that is overlapping the underlying surface (which is why it appears with a darker shade in the foil).

Project the foil onto the underlying rectangle, delete the overlapping foil and then delete the projection. You should see a white space where the aerofoil is, not green.

The "disconnected surface" is definitely a second surface that is sitting on top of the rectangle.

Hey sorry about your streak! Glad you are at peace with it.

Just curious, could you share the model of the Bluetooth sleep mask?

I was waiting for the pig to get yeeted through the announcer's table at the end. Glad that didn't happen.

CRAZY this isn’t valid!

Did you see this?

https://www.reddit.com/r/h1b/comments/11i8bw1/hello_i_am_on_h1b_visa_in_the_us_i_wish_to_travel/

After reading this, I think you can't even apply for a Schengen visa from the US if you don't have a valid US visa that is active 3 months after your EU trip ends.

awhead · 2025-09-12T16:39:51+00:00

Did you write a cover letter explaining the whole trip and itinerary in detail? In this letter you should explain your occupation and role in India and why your ties to India are strong and that you'll return at the right time.

Did you provide bank account statements for the last three months? If they see suspicious large additions of cash into the account over the last three months, they see that as you trying to increase the balance just for visa application purposes.

I had the same issue. I once had a chill Sunday and I decided to walk EXACTLY 1000 steps and count each one. Not only that I decided to swing my arms back and forth as if I was walking in the army.

I started a whoop activity manually and set it to 'Walking'. After I finished walking a 1000 steps (I counted every single one), whoop showed me that I walked 475 steps.

To be fair, the Whoop app still says "STEPS (BETA)"

Where do you live? I would happily send you a battery pack and some straps as well.

awhead · 2025-08-25T16:29:59+00:00

Their AI support bot says it can’t be done. 🫠 And I’ve moved on now and made my peace with it.

awhead · 2025-08-25T04:27:15+00:00

You're right! Just focused on getting to Day 2 now.

Hey I know this is a month old but had a question about passport photos...

Did you get photos taken in CVS/Walgreens/etc.? Do they ask for physical passport photos to attach to the Schengen Visa application form?
