  1. hi my dear The Plastic Strains are diffrent. but my goal is Decrease Displacement(Intrusion) -Intrusion cylander Speed : 8000 mm/s Although one of the models has a reinforcement part installed(Side Beam Crash), but the amount of displacement is the same in both models. best regards
  2. My Dear After completing the crash analysis,How can the contact force between parts be measured at Hyper View? Tank you
  3. Hi My Dear My mean of "is the same", the Boundray condition (SPC,Pole Speed, ...) are the same in two model. The only difference between the two models is that there is no reinforcement(without SDB.side impact beam) in one model and the other have reinforcement part. I expect the stresses in the two models to be different وBut that did not happen. Thank you
  4. Hi my Dear Attached are two different models of front doors that have been tested for impact. In one of the doors there is a piece of reinforcement and the other lacks it. But the result of the stress analysis of both models is the same, while it should be different. Please advise what is wrong with my work?(I thinkو I am wrong in defining the Interface Type7) Bestregards FR_Door.rar
  5. Hi My freind's When I run the Hypercrash program, An error has been detected and I am unable to execute it. Apparently, a number of required files have been deleted. Please send me these files or guide me according to the attached image to solve my problem. bestregards
  6. Hi my dear after Import LS Dyna file in Radioss and i convert to Radioss(Bulck format), I have some Error like below picture Please guide me, how solve this problem. Best regards
  7. Hi The Video file is not exist
  8. Hi dear friends Are Car models like Neon,TAURUS,Toyota YARIS (on the training site) complete and capable of analysis? Do they need to define a specific parameter to perform the impact analysis? Best regards
  9. Hi I share .rad file thank. FR_Door2_Gravity_30_0000.rad FR_Door2_Gravity_30_0001.rad

  11. Hello Dear friends In the attached model, there is an error in the energy balance(99%) I know that this error is related to how I define Material, Contact or Time step. But I don't know which parameter in the file I need to change to fix the Energy error. Can anyone advise on the problem of energy balance? Bestregard's
  12. Model with Impactor(Rigid wall) FR_Door2_Gravity.hm
  13. Hi my friend With your good help I was able to solve Mass Err. But there is still a fault with the energy error(ERR= -99%).I changed some parameter in my model(Contact,Material , ...).However, as soon as a collision occurs, the amount of energy increases.If possible, please guide me to fix this issue. Is there an educational film about this? Best regards and I hope to meet my good friends in the future.
  14. You explained so easily. thank you very much
  15. sorry, I forgot to send the files FR_Door2_E-5_0001.out FR_Door2_0001.out
