Can anyone please explain what this terms are. This is a snipshot from a radioss engine file. 

Also one more thing do we determine the time step for an analysis using the standard formula or is through a trial and error method of different time steps

Thanks in advance

    I believe this might be explained somewhere in Radioss training material or documentation.

     

    Anyway, radioss runs for many cycles. You can choose the frequency for it to show you what is going on in each cycle/timestep

    NC is the current number of cycles

    T is the current run time

    DT is the timestep of this particular cycle

    Error is the percentage error of the solution

    DM/M is added mass (delta mass/total mass).
