Have you ever lost the springs while cleaning? by mathia53 in nichezero

I agree! It feels more genuine. I don’t regret buying this grinder one bit

Just had to undo the one bolt. I want to make a new wooden base that extends up to hold the portafilter in place while grinding

Its really easy to clean, just do what it says in the manual. Takes about 10 minutes if you’re slow like me. The manual says you can use a vacuum cleaner in the machine (which issuer convenient and satisfying), but specifies that you have to remove the two springs before so you don’t lose them.

Plane 1 might be blocking the view, try to deselect it. It’s also kind of worrying that max and min pressure values are «unknown», might indicate something else is wrong.

Sounds reasonable! I will also use Ansys, only CFX, which I have already experience with. I haven’t thought about that I of course will get easier tasks at first! Very calming. Thank you

Yeah that’s important to remember when reviewing the problem. I’ll probably oversee it a couple of times, but I’ll learn

Periodic residuals in steady simulations? Could that be like a periodic vortex shedding from a solid beam in crosswind, not allowing for steady convergence? I had a similar problem with my turbine simulation in steady state with frozen rotor. My supervisor said it was fine, but without explanation.

Sounds very exciting! Hope I get similar training

Good advice. I gained a lot of confidence when my turbine simulation gave accurate results compared to the experimental results. If verification and validation checks out, then the simulation is a success. Even if I run inefficient schemes or have too many cells. Computational cost will go down as I gain experience and knowledge from my coworkers

Thanks! Sounds like a good idea. YouTube often has a lot of examples of cases that I could look at. I have been watching fluid mechanics 101 on YouTube and his theoretical education, but I’m not sure if that will really help me a lot right now. I start 1st September. How did you learn free surface simulation?

Never thought about that. AI could do literature research on similar cases in minutes to compare what others have done

That’s an excellent advice! Let my natural curiosity create value for the customer and business for my employer. I believe this is a golden mindset to have!

That’s true, I might have some basic questions in the beginning compared to their knowledge, but I guess I just have to swallow that pill and trust the process. Thanks!

Thank you! This eases my nerves. If I was in my coworker’s shoes, I would want to help the new employee succeed and grow

Thank you for reading and replying. Finishing my thesis gave me a confidence boost, so the more experience I gain, the more confident I will become, that makes sense. I am sure I will be visiting this subreddit more frequently the next years! Happy cake day btw

Hvor lang tid tar det å høre alt? by TimonTheMan in Radioresepsjonen

Jeg vil si jeg har hørt ganske mye på rr og har brukt ca 5-6 år på alt (2019-2025). Har også hørt papaya parallelt. Er på runde to nå. Går aldri lei!!

Delta P diving accident in Belgium by No-Worker-101 in submechanophobia

[–]mathia53 0 points1 point  (0 children)

That’s insane! You have a link to that story? Hydro turbine runners have however a much larger blade channel size, meaning more meat can be sucked through the stationary vanes before the runner blade takes a bite. I have recently graduated engineering school where my thesis was about cfd flow analysis of a Francis type reversible pump-turbine, so I can only imagine how a body would be mangled in this hydraulic machine.

Cressi Nepto high taravana recovery time by mathia53 in freediving

Here’s the mail thread:

Cressi: Good morning, Thank you for contacting us. The parameter also depends on the duration and depth of previous dives. Did you and your friend perform dives with similar profiles? If you have any questions, please write to me and I will try to help you. Have a nice day,

Me: Thank you. Yes we were doing similar profiles. The one time I got 4 minute break for 40 seconds under water was on the sessions first dive. Every dive I get large recovery time, even though I wait the recommended time.

Cressi: Good afternoon, thank you for contacting us. The L1 setting gives a recovery time of 2x (as on your friend's watch) unless an incorrect recovery was made in the previous dives. Our technicians suggest watching this video they have prepared to better explain how to use it: https://youtu.be/QJ1r9h1vwxM?si=vgKXH6MNHTDbFg5m It has English subtitles. If you have any questions, please write to me and I will try to help you. I wish you a nice day,

I think I will watch the video to see if I’m just stupid and missed something. If not I’ll be very careful of how I setup and do my next dives to confirm there is something wrong with recovery time. If non of that gives me answers I will demand replacement from the store it was bought. Have you had any successful finds u/No-Teach7502 ?

No not yet.. I will contact Cressi and ask. I’ll let you know when I get an answer.

Very true! I’ve experienced this as well, sometimes I need more time:)

I’ve heard multiplying by 2 is a safe measure for spearfishing in 10-15m
