Question regarding collision energy loss

Hi all,

i want to get the energy loss in my system during collision. I found in the help the way the energy loss is calculated but not what a negative/positive value is indicating. Am i correct, that a positive value means energy is lost in the collision and a negative value (e.g. during a collision with a moving mesh) indicating that energy is gained during the collision?

Thanks for clarification!

    Hi Clemens,

     

    The built-in version of the energy loss model actually gives the energy difference before and after the collision. If you're interested in the energy loss during the collision I'd recommend using the following API: https://community.altair.com/community?id=kb_article_view&sysparm_article=KB0120353

     

    Best regards,

    Renan

    Hi Renan,

    thanks for the script. I used the API as instructed. But i do not see the results. Where do i access them? I need to run the API with collisions also, right?

    Also regarding my previous question negative energy loss value indicates a energy gain, correct?

     

    Thanks and kind regards
