Problem with Energy Loss Calculation

Hi,

i have quick question. If i export Total Energy Loss values from collisions, i get a value in Joule. However, when i use a smaller time interval, the exported value for Total Energy Loss is also smaller. Why is the Energy Loss dependend on time step size of export?

 

Thanks!

    hi Clemens,


    For collisions the collision data is stored in memory and written to the file each save interval.


    So total collision energy is the sum of the collisions which have completed between t and delta-t (delta been the save interval).

     

    The total values at the individual save intervals would be different however the sum of these values over the total simulation time should be the same.
