Exactly. The side bar showing all my followed forums, each bolded when updated, was perfect. It was 1 click to get to new posts. Now I have to click 3 times, and cannot view a post while doing so — It's a new page each time, which adds 3 loading screens (which are also slower now, at least on my...

It sounds like you may want to transfer your data over to a spreadsheet. That way you can add the data for every LC and filter them as you see fit. I don't know why exactly you want to exclude certain cases from the envelope. Non "control" cases like 0.6D±0.6W are for checking sliding and...

Same statement does exist in Div 1 2023 ed. UW-20.1.1(d) "Determination of tube-to-tubesheet joint strength is not mandatory for U-tube construction."

It sounds like you want to use "Batch Solution of Marked Combinations". This will solve all marked LCs, and it allows you to toggle between the filtered envelope and the entire LC batch:

You should have your own copy. That is more of a legal issue though depending on ANSYS terms of service. Audits will usually look at the broad strokes of what you do. They may ask what software you use and leave it at that. I find client run audits will even ask for your validation of software...

Idan is absolutely right. Reading the code front to back, though not a bad idea, will not grow understanding, only familiarity. You should approach the code in context of problems needing answers. Find somebody experienced with the code and ask them for a sample of the calculations for a vessel...

UW-11(a)(4) does not apply: the nozzle thickness does not exceed UW-11(a)(2), and is not attached to head and shells falling under UW-11(a)(1),(2) or (3). UW-11(a)(5)(-b) states: "Category B or C butt welds [but not including those in nozzles and communicating chambers except as required in...

Loading the very end of the beam is also worth checking, as that will maximize loading at the beam connection there. Personally, I would check the crane at the start, middle, and end of the beam. If things are broadly symmetric then checking at only one end and at the middle should suffice...

Here the documentation link, seems like the quick reference guide leaves out the joints: https://docs.hexagonppm.com/r/en-US/CAESAR-II-Users-Guide/Version-14/346179

ASME B31J Table 1-1 should show them. Main difference is that "Welding" is actually a tee (a wrought fitting to B16.9). "Butt-weld" is for joints in the piping, which is only applicable for SIFs when there is an appreciable inner diameter change: Here are better descriptions for 7 to 13...

That depends on what you mean by "strength" and your code/application. Assuming this is for a ASME BPVC vessel: Section II Part D gives your allowable stresses, and you would use Table 1A for most applications (Sec VIII Div 2 and Sec IV use different tables). I've given them below: If for...

What is the question? It looks to me the situation is clear: Desired MDMT of -40°C, Curve B material: → 323.2.2(c) Assuming (1) to (3) all apply: Allows reductions of Table 323.2.2B to be used → 323.2.2(f) Requires impact testing below -29°C unless exempted by Table 323.2.2 → Table...

Let's say your MDMT is -40 (°C, or °F, they are the same at that temp). For a >2" walled tank, your test should be done at a temperature at least 30°F above that, so above -10°F, which converts to -23°C. Would you look at that, it's a 17°C difference. If you "converted" the 30°F like a...

I did some digging. These numbers come from "How Bad Are Bananas?: The Carbon Footprint of Everything" by Mike Berners-Lee. I don't have a copy, but looking at articles it seems these numbers include the "embodied carbon of the device it was sent on" which seems silly... Sending emails does not...

I've seen these numbers thrown around, but with no clarity on if this is generated by hitting send or if it incorporates CO2 generated by data storage for some time: Source: https://youtu.be/zvnVRg-Bi8A?feature=shared&t=478

In that case, you will need to reverse UG-37 to calculate a minimum tn. That will give your minimum thickness for reinforcement. I suggest: calculate your required area A and subtract the non-nozzle reinforcement areas (A1/3/4/5). That will leave you with your minimum A2, which will give you a...

Yes, the thickness tn is the thickness of the nozzle in the reinforcement zone, which in most cases will be the "barrel" thickness you have labeled on UW16.1(g) in the pdf. Just make sure it remains that thickness throughout the height of the reinforcement zone (else you will have to get...

It looks like it is calculating the maximum permissible length for a vessel with a 9mm wall thickness to achieve a MAEP of 1.03 bar (so roughly full vacuum). So it is not really relevant to your actual vessel, the program is simply telling you how long you could make the vessel. As for how you...

It will depend on local regulations, and most likely due to design pressure and design temperature.

It's clearly not conforming to an ISO or AWS weld standard, or else that would be an intermittent weld of 8 fillets spaced 8 mm(?) apart given that the dimensions are right of the fillet(?) symbol, which is neither sensible nor matches the drawing. There is also no all-around symbol... How...
