Article I think spring back prediction by using implicit is not realistic. What is your opinion regarding the convergence issue? May 19, 2009 04:38 PM
Article I just have one IGES file for the part, and I don’t want to offset the surface for the punch and die physically. Is it possible to offset the two surfaces internally inside LSDYNA3D? If yes, how do you offset these two surfaces? May 19, 2009 04:38 PM
Article I have no experience in springback prediction, and have no idea whether my prediction is reasonable. Do you have any idea how accurate the solution could be from LSDYNA? May 19, 2009 04:38 PM
Article I had no problem in running a forming job, however, when I used adaptive method, the contact does work properly even from the beginning without adaptivity. What is the problem? May 19, 2009 04:38 PM
Article I generated a dynain file after forming analysis. Additionally, I used DYNAFORM to trim the mesh, and did springback prediction. However, I found that the predicted springback is too small to be true. What is the problem? May 19, 2009 04:38 PM
Article I found that the number of adapted elements was too large when I performed a multi-stage forming analysis using adaptivity. Is there a way to avoid this problem? May 19, 2009 04:38 PM
