I have da cad model or a part of sheetmetal now i want to design a roll farming machine for that how can i unbend my cad model into 4steps toccalculate the machine dimensions

how did you decide which portion of plain sheet to mesh fine at bending zone?

Dear Romain, thanks for sharing this video. I'm wondering if you can share these following info: 1/ how many CPU did you use? 2/ How long does the simulation take? 3/ Which kind of time discretization method did you use? 4/ Did you use any damping to avoid oscillations at the front of the profile? Thanks you very much !

May I ask if you ever tried out a rollforming simulation with rotating rolls and friction?
