Hello Okkar,

LS-DYNA is continually evolving and it is possible to get different results with different versions of LS-DYNA. You may have to recalibrate your material models with newer versions of LS-DYNA to match the failure seen in experimental data.

Have you tried to save the input.k file in the R14 format with LS-PrePost before running with R14? This may help with the formating issue:

 

You can give more details about one of the examples you talk about and we may be able to better help you. 

If you want to use the same input files, the best would be to stick to the solver you used in the past (R11 for example).

 

Let me know how it goes.

 

Reno.
