I have "termination due to out-of-of-range forces" when running lsdyna. How should I solve this problem?

Hello, 

Error "termination due to out-of-range-forces' indicates that there is instability in the simulation.

Here are some general tips for how to combat instabilities:

Good practice is to locate where are the nodes/elements that give this error, it should be indicated in the message file (mess00XX MPP or messag -SMP), and visually inspect a model. 

Please let me know how it goes,

Thank you,
Alex
