• 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? — Welcome to the LS-DYNA support site
• 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? — Welcome to the LS-DYNA support site
• 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? — Welcome to the LS-DYNA support site
• 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? — Welcome to the LS-DYNA support site
• I have very long run times. What can I do?
• 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? — Welcome to the LS-DYNA support site
• I think spring back prediction by using implicit is not realistic. What is your opinion regarding the convergence issue?
• I tried to use LSPOST to compare the strain state with FLD. When I selected the element and clicked the plot button, nothing was plotted. What was the problem? — Welcome to the LS-DYNA support site
• I’ve found that when I use several CPUs with the SMP code that only one CPU is working and the other CPUs are idle. What is the problem and how can it be corrected? — Welcome to the LS-DYNA support site
• If a converged solution from springback prediction cannot be obtained after trying many different combinations of parameters, what else can I do?
• If I didn’t find wrinkling and strain localization in from my simulation, can I say that my design is good?
• If I use very coarse mesh for the pre-deformation (such as pre-bending, gravity loading etc), and then refine the mesh in the later forming analysis. Will it result in obvious numerical error for the final results? — Welcome to the LS-DYNA support site

• In implicit analysis of springback process, there are both linear and non-linear methods. Can you advise which one is better?
• In implicit forming analysis, I found that the friction force was not properly applied, what could have been the problem? — Welcome to the LS-DYNA support site
• In LS-DYNA, there are different material models and I’ve found it difficult to choose the proper material model. Would you please give me some suggestions in selecting the proper material model? — Welcome to the LS-DYNA support site
• In my analysis of the sheet metal forming process, I frequently found that the calculation could not continue and it terminated unexpectedly. Is there a way to avoid this? — Welcome to the LS-DYNA support site
• In my simulation, some of the corner nodes can be put in the wrong place. Can you advise what the problem is?
• In springback analysis I don’t have enough memory or the analysis takes too much time. What can I do ?
• In springback analysis, I found that my constraint hasn’t been taken into account during the simulation, what was the problem? — Welcome to the LS-DYNA support site
• In springback analysis, I just changed the constrained nodes a little bit away from the original node. The convergence then became very different and the predicted result seems not to be reasonable. What can be the problem? — Welcome to the LS-DYNA support site
• In springback analysis, we had no problem when gravity effect is not considered. However, after gravity effect is included in the input deck, there were some strange error messages. What might be the cause? — Welcome to the LS-DYNA support site

• When I a used drawbead in the forming analysis, it was observed that some of the elements which moved over the bead line were distorted, and there is no obvious reason for this effect. What might be the problem? — Welcome to the LS-DYNA support site
• When I attempt to do a springback analysis, I sometimes have difficulty in obtaining a converged solution. What options are available to improve convergence of springback? — Welcome to the LS-DYNA support site
• When I did dynamic relaxation analysis in gravity loading process, it took a long time to get a converged solution. Is there a way to make this analysis faster? — Welcome to the LS-DYNA support site
• When I did forming simulation, I found that a material failure was predicted earlier then expected, what might be the problem?
• When I do springback analysis, the prediction is not satisfactory. I didn’t find any problem in the input deck. What should I check to improve the solution quality? — Welcome to the LS-DYNA support site
• When I tried to trim the mesh after forming, the generated ‘dynain’ file contains the mesh without trimming, what is the problem and how can I fix it?
• When I trim the blank using IGES file, there is a message such as “Entity type xxx form 0 not supported # lines = x”. What does it mean?
• When I trimmed the mesh after forming, I only used one trim curve (in IGES format), but LSDYNA found 10 trimming curves. Accordingly, the result was not acceptable. What was the problem? — Welcome to the LS-DYNA support site
• When I use constrain method (SOFT=4 in the FORMING_ONE_WAY_xx card), the calculation terminates immediately, what is the problem? — Welcome to the LS-DYNA support site
• When I use FEA, I don’t know how big the mesh size should be. Would you please tell me what is the proper mesh size?
• When I use mesh adaptivity in my stamping simulation I don’t know how to define the proper adaptive frequency. Would you please give me some suggestions?
• When I use the implicit method to do springback analysis I cannot obtain a converged solution no matter what I’ve done. Do I have some other choices to obtain a converged solution for springback prediction? — Welcome to the LS-DYNA support site
• When I used implicit method to do springback analysis, the iteration information was not output or displayed in the screen. I think this iteration information is important for me to monitor the convergence status. How can I display this information? — Welcome to the LS-DYNA support site
• When I used switch method in my calculation, I used explicit method and then I changed to implicit method. In the later implicit calculation process, it was seen that the contact didn’t work properly. What was the problem, and how can I avoid this? — Welcome to the LS-DYNA support site
• When I used the seamless method to do both forming and springback analysis, a converged solution wasn’t obtained. I don’t want to repeat the forming analysis. Is there a way I can repeat the springback analysis from the previous output files? — Welcome to the LS-DYNA support site
• When the constraint contact is used, the calculation crashes during the forming analysis. What needs to be done to prevent this?
• When we do springback analysis, we have two choices to do it, i.e. using implicit and explicit method (dynamic relaxation). What is the advantage of using the implicit method in springback analysis? — Welcome to the LS-DYNA support site
• Why does the restart of the springback analysis not work?
• Why dynamic relaxation doesn’t seem to work at times?
