I am carrying out spring back analysis using LS-dyna and hyperform. The procedure as follows: forming is carried using LS-dyna and then the spring back is included in to the result file using hyperform and .k files are created using hyperform itself. While running the analysis, after certain number of iterations, the analysis aborts with message equilibrium can’t be achieved. I have included the both the input files (with and without spring back).
Please point out what could be the mistakes inthe input file and advice me for any additional inputs.
Thanks in advance.
Regards
Jacob
