Hello everyone, I hope you're doing well.
I am facing an issue with a simulation and would like to share it to seek a solution. To identify the cause, I conducted some tests using a portion of the complete model. The complete model consists of a casing containing a bundle of tubes inside, where the tubes are subjected to internal pressure.
When simulating only a part of the model, considering just the tubes, the simulation ran without any problems. However, when using the complete model, the following error occurs:
L'élément de plaque ne peut pas être orienté. Par défaut, pour orienter l'élément, on y projette l'axe global X.
L'axe de référence pour le calcul du repère local est ici normal à l'élément. Il faut donc modifier l'axe de référence en utilisant ANGL_REP ou VECTEUR dans AFFE_CARA_ELEM.
I have already considered the direction vector (0,1,0) on the clamped walls of the tubes, corresponding to the Y direction. I also applied the vector to the entire casing, but the same error persists.
I am attaching images of the part of the model that worked correctly (including mesh and results), as well as those of the complete model (mesh only), which is causing the issue. Additionally, I have included the .comm script used for the complete model.
I would greatly appreciate it if anyone has suggestions or ideas on how to resolve this issue.
