  • It looks like the problem was solved by using the last version of CCX: 2.14. I was using 2.13. The Allocate failure also occured with two older versions which I tried. Thanks

  • Thanks Sergio. So was I. For that reason I wrote "no problem" for the "102,400 nodes" case. I obtained the failure in the solving after refining a set of elements of the component, resulting in roughly 256,000 nodes.

  • I uploaded the step file. Thank you for sharing those test results. I do not understand: why do you point that "250000 nodes sounds like it could have been too much if..."? In all of these simulations I had plenty of memory available, according the…

  • Not, 10 GB free is not wrong. As I said, I increased the memory of my work computer. Now it has 24 GB, so the details about memory look like normal: with a problem around 230,000 nodes, 9 GB was the peak used by non-linear CCX solver, and many GB we…

  • I think I was not clear about the memory. I meant that during the solving calculation, the memory used by Mecway is growing. And at the peak of its memory use, the computer had still 10 GB free. Ok, perhaps I will try in that group of Calculix. Tha…

  • I have the impression that that wrinkling corresponds to Internal pressure + Axial compression. Anyway, your last answer clarifies better the problem to me. Thanks

  • Thank you, Victor. I know that buckling can appear when a cylindrical shell is subjected to external pressure. There is much literature on this topic (Rathinam et al. 2015, Teng et al. 2006, for instance). Although I do not find papers on buckling …

  • Hello disla, "I can’t figure how did you manage to couple different element rotations through coupling using the dot product formula" As Victor replied, the dot product-formula was intended to measure rotation, not to impose rotation. In this res…

  • Yes, I understand those formulas. As you point, that is "the easier case of rotation angle about the global origin". I was trying to confirm that it is not possible to build a single formula for the general case: when the center of rotation does not…

  • Thank you for your precise answers, Victor. 1. Finally I was able to couple the rotation through beam elements. 2. Ok. I had no problems with that cylindrical sliding. 3. I only have still a question on this issue. Is the formula addressed to each …
