    Hi Nataraj,

    Is it energy error or hourglass energy?. In a crash simulation generally there are no chances of negative hourglass energy.

    If its hourglass energy, please upload a snapshot of the global energy curves (internal energy, kinetic energy, total energy, hourglass energy and contact energy curves in a single plot).

    Thank you for your quick response.

     

    I don't have any snap of Energy Graph.

     

    I wanted to know can it go negative by any other parameter in crash simulation.

     

    Thank you in Advance.

    Hi Nataraj,

    Normally hourglass energy will not go to negative values.
