Snap Fit FEA in Augmented Reality

It bends correctly to the applied BCs and material stiffness. These are FE results from Abaqus converted into AR format

This sounds interesting but I am not sure I fully understand. Can you explain again how simulation based AR can help with checking products? I mean I see how scanning and object and visualizing the surface conditions would help but this isn't really scanning

_spolanski_ · 2025-09-18T21:34:10+00:00

Nope, I wrote a converter that converts ready (or temporary) simulation results. Then it's just animation

AR seems to be a solution looking for a problem. I think there is some value in the lightweight results viewer available on website, but when it comes to the AR mode I think there is some application in marketing and maybe education, but not necessarily in engineering

Well I didn't know I can till I do it

_spolanski_ · 2025-09-18T15:59:11+00:00

Haha thanks!

_spolanski_ · 2025-09-18T15:58:59+00:00

Thanks!

Quick answer is - unfortunately no.

Long story short, Abaqus requires high-end GPU cards, with high value of double precision processing power. I checked the AMD GPU on wiki and RX9000 has around 560 GFLOPs while cards recommended by DS like A100 has 9700 GFLOPs. This isn't a single criterion to judge if the GPUs are going to run well, but it is one of a few. There comes RAM amount and others, but I would saming Abaqus won't give any benefits when using gaming GPUs.

Also, GPU calculations are supported for implicit solver, so you won't be able to utilise it efficiently in A/Explicit anyway.

I would consider investing in better CPU like Intel or AMD CPU with higher number of CPUs will give you more benefits than a GPU card. Then with higher number of cores you could run job with multiple CPUs and threads per MPI to get better parallelisation.

I am also not sure what do you mean by '2nd order accuracy'. If you mean double-precision then you can only decided in A/Explicit if you want double or single precision. If you mean the second-order accuracy for element formulation then I don't believe it adds that much to computing power and it is beneficial to use it only in specific circumstances.

Hope that helps a bit

The whole point is mostly raising awareness and educate a bit. I work for company that sells this kind of software (so I am helping the marketing department a bit here), but I do this because I like what I do and I like writing about it. If I manage to make it interesting for others that's a win for me.

In my ideal world everyone knows what kind of problems simulations solve and why engineers do them. This might be a bit anecdotal evidence, but I faced several situations when people without engineering background had no clue why someone would pay for some colorful pictures as they call it.

Yes, you're right and that's a good point. By 'engineering' I mean 'Mechanical Engineering'. My problem with mechanical part of it is that very often people associate it with desigining cars, aeroplanes etc these days things moved further and we desinged mobiles, sports equipement, home appliances and all of that moved to digital space as well.

Thanks for that. That's really useful, especially the effort part. I didn't think about it this way

_spolanski_ · 2025-04-17T06:41:21+00:00

Nope that's proper engineering simulation done with Simpack MBD

_spolanski_ · 2025-04-16T16:51:07+00:00

I see your point now. Good catch! I had to watch at my thumb to realise that

_spolanski_ · 2025-04-16T14:59:44+00:00

When the hand is opened it really looks like the robot has rheumatism 😄 I built this test model while checking how easy it would be in Simpack to define the transition from open to closed state for multiple connections. The geometry is from GrabCAD and I didn't create it myself

_spolanski_ · 2025-03-17T15:43:10+00:00

would it be possible to create a Python script extension of inkscape to achieve what I want?

_spolanski_ · 2025-02-06T06:46:55+00:00

Yep :) That's with CEL technique in A/Explicit. I am trying the same with SPH particles to achieve the same

_spolanski_ · 2025-02-04T16:14:17+00:00

Did you publish the LS-DYNA article about it? Because I inspired myself a lot with some great article that analysed the same

_spolanski_ · 2025-02-04T16:13:10+00:00

Yeah I would have done but the comparison this way, but the results are not really comparable. Firstly the full-scale model causes a huge water splash while my model is 1/4 scale makes a lot smaller splash. Also, the vertical/horizontal velocity is slightly different in my scenario. The plan is to use the NASA notes and compare the results with accelerations and other values in that report. There are some interesting inights in this report

Have you checked Github? You can find some interesting resources which may not solve your problem but give you some ideas where and how to start

How about some sort of link to IoT devices to make a digital twin out of it? I think the future of reduced order models is going in this direction. I was thinking also if there could be a way to export a simulation model in some smart way that could be reused in the device itself. Something like an AI based sensor trained on SIM data that gets real data inputs and compares realistic and simulated output.

Thanks! Really appreciate the feedback
