I am trying to prepare a 1\/4 model simulation of a ball impact on a composite plate modelled using Tshell elements and with tiebreak contacts. I managed to successfully run an identic model to the one I want but with shell elements, however when I apply the exact same conditions, only changing from *ELEMENT_SHELL to *ELEMENT_TSHELL (by modelling each ply with Tshells with EleGen -> Solid -> Shell_Thickness, as in this video<\/a>) and from *PART_COMPOSITE to *PART_COMPOSITE_TSHELL, the simulation ends within the first timestep, with all parts disappering. I have tried to run the simulation with different Tshell formulations, but none of them worked, and I cannot identify the issue(s) that contribute to the error. <\/span>Any assistance you can provide would be greatly appreciated.<\/span><\/p>\n

P.S.: I though it would be possible to upload the keyword files of both simulations, but I could not find how to do it, you can find them in this Dropbox link<\/a>.<\/span><\/p>\n","protected":false},"template":"","class_list":["post-287012","topic","type-topic","status-closed","hentry","topic-tag-compositematerials-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
