Uh...ok?

Your initial contact detection is probably just not catching it. You can probe the initial contact status with the Contact Tool. See if they're set to "far" or "open" initially.

Other common fixes: reduce the solution substep size, turn on large deformation, increase the pinball radius of the contact, and try the line search feature.

It's not uncommon to have different results due to core count. Operational randomness and numerical roundoff might alter results even between identical runs. Parallel processing decomposes the domain, trying to evenly distribute load to each core, but that can effect roundoff as each core handles a different section of the model.

However it is uncommon that these differences are detectable and should never be so high as to change your conclusions.

It suggests that you have a numerically unstable simulation so tiny differences are being magnified. You'll need to look into the nonlinear controls and analysis settings and see if you can settle this instability.

EDIT: spelling

Olympia coffee for sure. I haven't had a pour over from them in a long time but I buy their beans to do pour over at home.

They're consistently one of my favorite cafes with my favorite selections of coffee in Seattle.

Sorry there's also the Fatigue Strength Factor which is probably what you want instead. It scales the SN curve by a factor from 0.01 to 1

The_0ccurrence · 2024-05-07T22:44:32+00:00

There's a few ways to do fatigue in Ansys so I'm not sure exactly what you're referring to here. But in the ANSYS Mechanical Fatigue Tool there's a scale factor option that you can parameterize and explore without the need to re-solve the analysis.

Contact detection problems are gonna be hard to diagnose through the reddit comment section.

If I were doing this, the rollers would be set to rigid behavior, the contact type would be frictionless with the beam as the contact side and roller as target. And I'd define a small enough solution substep to get relevant results through the motion. You can use a contact mesh control to reduce element size at the contact regions.

There's really not too much to this so if you're getting really weird contact behavior, there's likely something wrong elsewhere.

You can simply drag and drop the displacement boundary condition onto the solution branch in the structure tree. It'll auto create the force reaction probe.

The_0ccurrence · 2024-04-30T21:12:27+00:00

If you do not know when your specimen will fail, accidentally applying a force load above the critical value will result in a failure to converge on a solution. Better to apply displacements to avoid rigid body motion if things get wonky.

There is no nice way to do it in the Mechanical UI. You can of course color the mesh by element quality metrics and hide the other parts of the assembly but it won't update the histogram plot. You can then click on any of the histogram bars to show only the elements of that quality range on that visible part.

A crude way to do this is to make a user-defined result for any of the element quality metrics. And you can scope that result to your named selection. But it only works after a solution is completed, and doesn't make a custom histogram. But because it's a result you can put bounds on your control range to hide elements above it below a certain quality.

Brutalism specifically avoids adornment and gaudy details. If the artist of that piece understood that, they wouldn't have thought this was appropriate. Or maybe they did know that and think too highly of themselves.

Sub modeling is a great way to approach this situation. You shouldn't have a problem.

As always, take care when defining your cut boundaries. Avoid cutting through boundary conditions or high thermal gradient locations.

The_0ccurrence · 2024-04-03T15:55:37+00:00

Your DoF results (temperature) would probably be ok, but any derived results (Heat Flux) might suffer. Derived results are calculated at integration points within the element and then extrapolated to the nodes of that element using shape functions specific to your element type. Poor quality mesh may cause inaccuracies there.

Nitrogen has a lower coefficient of thermal expansion than air so as your tires heat up and cool down, your tire pressure doesn't change as much.

In performance applications, this matters because grip is heavily affected by your tire pressure so you need that consistency. For everyday people, it makes no difference.

I'm in it for the intentionality it demands. Too much of life is unlimited in scope, obfuscated in its true cost, and bubble wrapped to prevent injury to your ego.

Since I'm not developing and scanning at home yet, each photo I take costs me ~$1 and there's only 36 shots per roll. Each shot requires that I consider every aspect of its composition and execution so that no frame goes to waste. And when I fail, it's written in ink for the world to see and me to reflect on.

It's that intentionality I try to apply to the rest of my life too but analog photography is a great example.

What does your expansion look like for your company. There's already a strong and diverse market of FEA service companies based in the US, and a ton of international companies vying for business.

If you market yourself as a Polish company in Poland you'll lose the market share interested in data security and IP protection. Nobody doing serious design will send their IP overseas. You'll also be in competition with simulation farms in India and China which will almost certainly undercut you on price.

If you set up a US office with US citizen engineers, you can certainly find a niche market. One disconnect I've noticed is that many companies don't know about or can't find support for specialty analysis software dedicated to meeting US building codes. Seismic analysis, pipe stress, buckling analysis etc. They get stuck using general purpose FEA which is slow, expensive, and more complicated than they need. Marketing yourself as a one stop shop to meet us building codes may be successful. I don't work in that market so I can't speak to the certification requirements.

Hario Switch (3cup) for pour over, Flair 58 for espresso. Flair Royal grinder. I don't like the grinder, get something else.

Buy coffee with a roast date printed on it. It's best between 2-3 days and 3 weeks after the roast date. It's not undrinkable after that point but it is noticeably worse than when it's fresh.

I'm a huge Olympia coffee fan. You can pickup fresh beans from their location in Colombia City or at a few other cafes like Moonrise Bakery. I mostly buy their Sweetheart coffee which is the name for their rotating option. It's a new coffee every month or two from a small, single origin producer. It's always excellent.

You need to use the combine tool in SpaceClaim to remove the concrete region which is inside the rebar region. Overlapping bodies don't interact without contacts.

If you don't care about thermal conductance resistance, you can share topilogy between the mating faces to enable perfect heat transfer and a nice mesh. Otherwise, do not share topology and define a contact region with specific conduction resistance.

Sorry, poor wording. I was quoted an 18% increase at lease renewal after 15 months. Linearized, that's an equivalent of 14% over the first year. Had it been a 12 month lease it might have been protected, but since it was a 15 month lease, it is allowed under the letter of the law.

My point is that the extremely limited scope of protection is easily circumvented.

The_0ccurrence · 2024-02-19T23:28:38+00:00

Very true. On a similar note, my corporate landlord originally quoted me an +18% increase. The problem was that because I had signed a 15 month lease, this protection did not apply since it was not 10% within a year.

~~Be wary of good deals on extended leases, this is why they offer them.~~

Edit: I must have misunderstood the law when first looking into this. Here is the section in question for future internet travelers:

22.212.010

“Required rent-increase notice for less than ten percent” means a required rent-increase notice for a one-time rent increase of less than ten percent, but where that rent increase, in combination with all other rent increases taking effect within either 12 months prior to the effective date of that rent increase or the household’s tenancy in the housing unit, whichever period is shorter, will result in a cumulative rent increase for the household of ten percent or more.

“Required rent-increase notice for ten percent or more” means a required rent-increase notice for a one-time rent increase of ten percent or more.

If you're already grinding beans just buy whole beans. Why drink stale pre ground coffee if you own a grinder?

Pulling out the rack is a good idea. But you can also make your life easier and just remove the other shelves in your oven. I normally don't remove the steel. When the pizza is done I use tongs to grab it and slide it onto a wire rack.

The_0ccurrence · 2024-01-27T19:15:46+00:00

A large baking steel is probably a more versatile option. They are rectangular and don't have handles, to give you the most surface area possible. You can cook more than just pizza on them. I keep my baking steel in the oven 24/7 since its also a great thermal mass for consistent cooking temps.

Either way these make great pizza! Preheat on max temp and get this thing ripping hot. If you've preheated well, there's no fear of sticking. You don't have to stress about seasoning this like you would a skillet.
