  • Thanks, glad I could be of some help. I know it's a bad model, I just made it to see how big I could go with Mecway. And there is also CCX (under Linux) as an option for models of that size.

  • Thanks for the quick reply! Your model works fine on my machine and I am using the 64 bit version. I have attached the model. It's about 5 times larger than yours with parabolic elements, maybe that has some effect.

  • Barrti, Just a few tips you might find helpful. With plastic analysis like these, you should be looking more at strains instead of stress, which are likely very high at the bend. Idealy, you should also use an actual stress-strain curve instead of …
    in Sheet Metal Bending Simulation- Non Linear CCX , Steel Strip using Contacts Comment by simon October 2017
  • Sergio, After a bit of tweaking, I got your model to work with both elastic and plastic material. What caused the "explosion" seems to be the contact not converging. It can go the full cycle up and down, but with automatic time stepping it does no…

  • Thanks Sergio. Do you know if the linux version more stable than the windows one?

  • After some digging around, I found answers to my questions. *There is no real difference for (optimized) build of CCX2.10, 2.11 and 2.12 under Windows. *Under a less than optimal Linux set-up, I have seen 5-20% faster computing than in windows. …

  • That's what I was expecting as well, I just wanted to make sure I wasn't missing anything obvious. Thanks!

  • There are no incovenience at all, I was just testing the new version. I am running a i7-4820k, 64GB RAM, win10 64bit home. thanks!

  • kwip, I have some issues with some of your executables. CCX 2.10 and 2.12 MTNO work without any issue, but 2.11 and 2.12 MT crash immediately upon startup. I only get a generic Windows pop-up that the program has stopped working, with no more in…

  • The tet shaft is more in line with a real world analysis in terms of shape and number of boundary conditions. I made the plate one because I had some problems with the tet mesher getting model sizes that were relatively close together. The half-cyli…
    in How many nodes can you work with? Comment by simon June 2016
  • Hi, I put together a table comparing model size versus run time and memory use for Mecway, CCX 2.8.2 and 2.10 (kwip version) for parabolic elements. The first two models are probably more representative of an actual FEA model, the third one is jus…
    in How many nodes can you work with? Comment by simon June 2016
  • Thanks Sergio for the tip, CCX works much faster now I don't have any specific need for big models, I'm testing Mecway and trying to see how big I can go. I'll put a table together when I have more results, but right now I would say that everythin…
