OpenRadioss
Problem with plasticity using user subroutines for materials. #3301
-
|
Hello, while solving the Cantilever Beam problem with user materials and calculating plastic strains with Radial Return method, i have a problem with plastic strains: on some elements they are equal zero, where it shouldn't be. While the stress and strain distribution are continuous.
I tried to set the static plastic strains for all elements, and have the same picture: on some elements it was still equal to zero at the same elements, while it was setted 1.0 for all of them.
Looks like OpenRadioss skips some elements, and what could be done to solve this problem? Maybe something with element buffering size, but cannot say properly. |

Hi @greazee, It looks ok for me (I do not see these artefacts):
Maybe it is an issue with your postprocessing tool ? Thanks and best regards, |

But with Plastic stain, I can see it, too. Will have a deeper look, now. |

Hi @greazee,

And indeed, it was due to a bug, which was introduced recently.
Thanks to your hint, it was fixed few ours ago.

(on my side, it shows correct results, now)
Thanks and best regards,
